Hi guys,
After seeing Phil's laser pointer in action (5mW) I decided to jump on ebay and snag one. I saw a 240mW one, and got it for about $90 including shipping. :screwy:
My question is: Is there a power limit to lasers enforced by law? I read some articles online that said Oz DOES have a limit of 1mW, but it was an old article, I think. 5mW seemed quite powerful, so I have no idea what 240mW would do to my eyes! :eyepop: I'm hoping it's a dud and not really 240mW now...
This is the item I bought last night.

Any thoughts??? :help:

I have a 5 which is quite sufficient for my use. If the ambient light is pretty high the beam can be difficult to see some times, but generally it is a great tool.
Be careful not to do anything stupid with it, I would hate to have them banned and make them even more restricted than they are at the moment (I have my 5mW registered with the Victoria Police). The legal limit is still 1mW, above that it is restricted.
anyone point me to the law for NSW, too lazy to look it up...
DJVege
12-04-2007, 01:25 PM
:D :) :shrug: :sadeyes: :(
Hmm...I thought it was 1mW. I think I'll just keep this 240mW in a safe place (with no batteries) and pick up a 5 or 10mW one.
By the way, who do I ask regarding registering a laser pointer?

There doesn't seem to be consistent legislation regarding laser pointers.
There is a standard, AS2011 that covers the classification of lasers and is available for purchase from Standards Australia.
I want one that can blow my neighbours light bulbs on their
verandah.:evil2:
They seem to be permanently on all night now.:tasdevil:

It seems someone recently asked the Police Minister the same question in Parliament.

It is illegal however to sell them if they aren't appropriately tested. I hope our friendly scope retailers have looked into this!

Going on that Ebayers reputation, you might get it this year,,,,24 negs in one month,,,,:shrug:
If you buy any lasers on ebay, they're probably by crappy companies.
I WARN YOU NOW:
Any lasers you buy on ebay for less than $100 that are up in the 100's and 200mW's DO NOT HAVE INFRARED FILTERS!
DO NOT BUY THEM! THEY WILL RUIN YOUR VISION! INFRARED IS INVISIBLE AND AT 240mW FOCUSED, LESS THAN A SECOND IN YOUR EYE WILL BURN OUT YOUR RETINA!
These lasers start out at 808nm invisible, or near invisible light, they are sent through a Nd:YVO4 crystal which then brings the light to 1064nm (INVISIBLE) and then it's sent through a KTP crystal which doubles the 1064nm to 532nm visible green light.
I'm guessing with that 240mW you bought for $99, it's outputting less than 10mW of 532nm collimated green light.
I've been around lasers a lot, I know a lot about them and I own ones that give out true 380mW 532nm light. I also have a few more green lasers less than that power (130mW and 95mW). I am also a photographer for http://www.lucentoptics.com that supplies high powered green lasers.
I also know that in United States, lasers above 4.99mW are illegal to be used outside of your own property, and cannot be pointed in any airspace.
If you have any questions about lasers, please feel free to contact me or ask any questions in this thread.
Here's some pictures of my lasers that were taken by me:

Also, don't buy from Wickedlasers. They're overpriced and the chanches you'll recieve a broken one is probably 1.5 in 2.
DJVege
14-04-2007, 12:40 PM
Hmm....where are you at Ingo? It would be good to get the laser looked at by someone in the know once it arrives.
...DJVege...
I'm in United States. Upstate New York to be exact. You can sometimes see the IR filter. If it's there. You can look down the barrel aperture (TAKE THE BATTERIES OUT FIRST TO MAKE SURE OF SAFTEY) and see if you see that color. If not, I'd send it back and get your money back and buy something from like lucentoptics.com.
The IR filter looks like this:

If you contact the company it's made by, they will tell you a lie.

i believe in NSW it's 5mw for a laser pointer. Those high powered ones however are laser modules which allows them to get past that limitation.
if you are interested in one. DON'T buy off ebay as most of those don't have ir filters.
http://www.wickedlasers.com/
these guys are the most reputable and will give you your money back if the laser doesn't get past customs.
I would not recommend buying from Wicked Lasers. These guys are well known scam artists, that make a ton of money. I've been around them a long time, I was once their official photographer. Nobody ever receives their lasers up to spec and they released their new Evolution series about a month ago. ONE person has received a laser that was up to spec.
Also, wicked laser type pointers are overpriced, and there's a duty cycle unless you feel like spending $2000 on an overpriced laser that wont even be up to spec, and will most likely be USED before you receive it.
I'd recommend lasers from http://www.lucentoptics.com, http://www.optotronics.com, and http://www.laserglow.com/.
All of those sites test their lasers for output before going out, unlike WickedLasers.
interesting ingo! thanks for the headsup on that!

23-04-2007, 09:57 AM
Thanks for the info guys. Firstly, once I get my ebay laser, I'll pull it apart and look for the IR filter. I'll let you know my findings. If it's crap, I'll get a 5 or 10mW laser from one of the websites mentioned above.
Thanks again.

I've never had a problem having bought a pulsar and nexus from them.

The nexus, I doubt it's outputting more than 75mW.

People have been turning up at Cambroon with 20mw laser pointers, I have a 5mw one and there is very little or no difference, so buy a 5mw and save your money.
In my opinion there is no value in higher power.
Just my two bobs worth.
xstream
24-04-2007, 04:09 PM
I have to agree with Ron, There is no real benefit in getting a higher power laser. 5mw is more than bright enough.
jjjnettie
24-04-2007, 09:23 PM
Yep, Ron's right.
We were dueling lasers the other night, and his 5mW was as strong as my 20mW.
I could have saved myself $40.
You need 2x the power, for 1x the visible brightness. So 20mW should've looked slightly brighter. If not, your 5mW is not 20mW.
Often cheapies aren't real power.
astroron
24-04-2007, 10:10 PM
So is the SLIGHTLY BRIGHTER WORTH THE MONEY?
Ingo, I think you meant to say your 20mw is 5mw, is that correct?
Yes, thanks for the correction.
Brighter may not be worth that much more money for astronomers as they can be distracting and make other astronomers angry. Laser enthusiasts will want more power to burn stuff, which also comes out to be a lot brighter.

25-04-2007, 11:15 PM
Ok guys. I got the laser pointer from ebay today. Here are my initial findings:
1) This definitely ISN'T a REAL 240mW laser, as it doesn't burn anything. However, it is VERY bright!! There is no heat coming from it, either.
2) I don't know how to take it apart to look for this IR filter. I tried looking down the barrel of it, but I can't make out anything. Any ideas on how to take this thing apart?
...DJVege...
240mW should burn your hand in an instant, no matter what color you are. My 130mW does instantly. So I'm guessing you're getting maybe 10mW of green light, and 240mW of unfocused, very harmful 808nm or 1064nm invisible light. Usually they're 250mW pump diodes and they put 240mW there because they're unfiltered and actually do give out that much light, but it isn't all visible.
If you'd like to keep your eyesight, I recommend buying a IR filter off of eBay that'll fit over the aperture of the laser to protect your vision as not even a second at 240mW will damage your eyes forever.
Yeah, that was when they were a great trustworthy company with great products, but now they have gone bad and scammish.
of course ingo, you dont sugest trying to burn yourself to see if a 240mw is what it says it is :)
I have a 10mw, its plenty.
Well, it's a slight sting. It doesn't permanently burn :thumbsup:
DJVege
26-04-2007, 11:54 AM
If I look down the barrel, there SEEMS to be a bluish colour....:shrug: I can't take it apart, though. How would I get an IR filter in it, if it needs one?
That could just be lens coatings. If you want, just glue a IR filter, or you can try to manufacture something that'll go over the end, and hold the IR filter.
I think it's a lot better than losing your eyesight permanently .

I have been reading this thread ever since my return from holidays and was myself thinking of getting a ebay cheapy....but after all the bad things I have heard I don`t think I will bother..
Does anyone recommend any sellers in Auzz? Are the Andrews ones what they are quoted at and good brand name?
One thing I have noticed also is the beam widths are different with lots of them? Would a 5mw with a .8mm beam be brighter than a 10mw with a 1.5mm beam? and the quoted rad value is it better the lower it is?
I need it to work under dark and also clear air as I don`t have too much pollution and haze at home so still wondering if a good 5mw would be plenty?
Cheers Gary
DJVege
26-04-2007, 09:42 PM
I'm just a noob, but I'm VERY certain that you should go no higher than 10mW. It's more than enough. I'm sure someone can tell you which of andrews, bintel etc... are better.
Cheers.
...DJVege...
A 5mW with a .8mm beam will be brighter than a 1.5mm beam. There is more light condensed into an area, where 1.5mm is more spread out. Also a thinner more focused beam is better for burning.
mRad is milliradius and that shows you divergence. The lower the number, the less the beam spreads in distance. Usually, you'll get <1.2mRad.
20mW is more than enough for astronomy, but if you want something to stand out and make other astronomers jealous/mad, check out lucentoptics.com, they'll ship anywhere :lol:

The two main reasons people go to ebay for laser pointers is cos of convenience and low prices.
In the end you normally end up out of pocket and don't even have a laser to show for it.
Lasers are missing IR filters which makes them dangerous and gives exagerated power readings. The lasers are also often pot modded (power is boosted) which makes the lasers unstable and likely to burn out.
Unless you are buying from a seller with an established rep, stay away from ebay.
An excellent alternative is Dragonlasers at www.dragonlasers.com (http://www.dragonlasers.com)
Their prices are pretty much as low as you can get for a genuine high quality laser pointer and they have outstanding customer service.
They even sell lasers that have no duty cycle and an on/off switch which makes then ideal for mounting on a telescope http://dragonlasers.com/hulk
dragonlasers.com are good. They started with a bad reputation but have since built it up. Their pen pointers are made by CNI, and I recommend you stay away from them. The PGL III's are also made by CNI, but are better quality.
Soon lucentoptics.com will have the PGL III's for a lot cheaper than dragonlasers.com. Right now they sell the smaller PGL IIIa's.

DJVege
07-05-2007, 07:16 PM
Hey mate, did you get it from "i.web". A few things you can learn from this thread:
1) There is no way you will EVER get a REAL laser POWER higher than 15mW from ebay. It may be a 240mW diode, but if you shine your laser onto some plastic and the plastic isn't burning in under 5 seconds, then it's not a true 240mW laser...just a 240mW diode.
2) That laser you have is dangerous because it won't have an IR filter. I haven't been able to pull mine apart to check, but I'm fairly sure it doesn't. You can still use that laser, but because there are wavelengths coming out of it (invisible) that are extremely dangerous to your eye sight, it would be best to buy one from your local astronomy shop (I haven't heard any reviews on Bintel, myastroshop, telescopes-astronomy etc... and their lasers).
In any case, read this thread and you should get all the info you need.

Hi all,
Just to clarify a point re:
"mRad is milliradius and that shows you divergence. The lower the number, the less the beam spreads in distance. Usually, you'll get <1.2mRad."
mRad actually stands for milli-Radian (1/1000 of a Radian). Radian is a unit of angular measure like degree is.
1 Radian. = 57.296 degrees
1 mRad = 0.057296 degrees = 206.26 arc secs.

Gee, I was going to buy a green laser 3 or 4 weeks ago then started reading this thread and decided to wait till the dust settled and there was a definitive best buying option for the average bloke who wants it 100% only for pointing at stars during an observing session.
So for $50.00 bucks is the one at Andrews a good buy?
There are good ones on ebay. "Atlasnova"...they're "Leadlights" and can be modded easily up to 20-30mW.
They're 4.99mW 532nm Green Lasers for about $40USD

Ingo,
You appear to be very knowledgeable about lasers, I hope you can help me.:D
I have a 20mw laser that works very well hand held, but if I mount it in the Scopestuff mount I have and leave it in the (not very) cold night air the beam vanishes.
A friend of mine has a cheap 5mw laser, mounted on his Scope. He can use it in very cold temps and it fires up instantly with a healthy beam every time.
What's the difference? I use freshly charged AAA NiMh batteries.
Thanks, John.:thumbsup: :thumbsup:
It could be it's a modded one and it's sucking up the batteries really fast because they pull a certian mA. The diode is probably turned up, sucking more juice than it is supposed to.
I'm not saying it is a modded one, but it could be the cold. Cold will shift the wavelengths the diode gives out and the Nd:YVO4 crystals require exactly 808nm. If it's too cold, it wont give out the full output due to efficiency loss and drop in wavelength to maybe 807.7nm which wont lase fully.

Its safe to say that you are not going to be hunted down by the police just because you have an overpowered green laser pointer. That is, if you use it in privately and do not use it to cause a disturbance. Its common sense guys, take a 1mW laser pointer outside and shine it on some cops, it'll end you up in jail. Take a 300mW Wicked Lasers Spyder II GX outside on the Meade and shoot the stars, careful with the planes and you'll be alright. I tried that Dragon Site, they paid me to spam the internet, but they screwed me, so I don't suggest them anymore. The most trusted sites are abeland1.com (low powered) and wickedlasers.com (high powered) for green laser pointers.
Gargoyle_Steve
11-05-2007, 11:32 PM
John another thng that could be affecting yoru laser output is the batteries you are using. rechargables - be they NiCad or NiMH - only put out around 1.2v each whereas any non-rechargable (any that are not flat anyway) put out 1.5v each. So if your laser is like most and uses 2 batteries, you've already robbed it of 0.6v of the 3v supply it's designed to run on - you're trying to run it at 80% power by using rechargables.
Also batteries are affected by the cold too - some batteries will provide way below their "normal" output power when cold. Dewstrap heater for the laser maybe? ;-)
Wickedlasers are scammers. Their Spyder's are overpriced, and underpowered. They are also they are certified as 200mW's, not 300mW's like you said in your post. I would not recommend anybody buy from WickedLasers because you will receive a very crappy laser that certainly isn't what you paid for. You can get a 400mW laser from laserglow for cheaper than the Spyder GX's.
Also, if you want a blue one, it's TEM30, not TEM00, so it's 3 beams because their company is too much of a rip off to make it TEM00.

Hi All,
I bought a 20mW green laser pointer from Bintel. The first one was a dud - it would would fade very quickly (say after 30 secs) Bintel said its a common problem. The replacement works well all the time (very bright!), but Duracell batteries probably last only about 10-20 mins. So if i use it mainly in momentary mode its fine. I bought it for $129 and consider it ones of my best buys. Fantastic for teaching my kids and others and I've mounted it on my scope which tells me exactly where I am in the sky (I'm a beginner).

Interesting, at the candlepowers forum there is a member with the name luvlasers. He/she has a laser from Dragonlasers and i've read a couple favorable reviews from him/her on Dragonlasers and Laserglow.
Are you the same luvlasers with a sudden change of heart or just a wickedlasers fanboy borrowing the name to flame a competitor.
I would not go as far as Ingo to say that wickedlasers are scammers, most companies have their strengths and weaknesses. I would say though luvlasers or who ever you are that you are scamming. So how about you make a constructive contribution to this thread or find another rock to hide under.
Now back to the thread topic.
Looks like more than 1mW is ilegal in Vic and fine in NSW. What about anywhere else?

1.I'm only a high school student but i have been studying physics, which is the best kinda laser to burn things within a reasonable price? (i am still a silly student and love fire:P)
2. if wicked lasers (the place where i was gonna buy a laser form) is a scam where can i find a decent laser site either in australia or somewhere i can ship it from?
3. what is the laser clasifications in queensland? are they different from nsw and vic law?
4. when i get my laser is there any safety equiptment i can buy that can protect my eyes e.g. in wicjedlasers.com they have safety goggles.
5. are there accessories that can make my laser even stronger?
6. even though it is not safe is it possible to play skirmish with lasers?

I think you'd do better searching other forums. Lasers are a sideline to the main interest of astronomy, IMO. There was a fairly long thread in the Whirlpool forums. Do a search on lasers there.
I'm amazed a high school student afford $2500 for a laser (and slightly dubious ;)). Most of your questions can be answered with a quick Google. But I'll bite on a few...
1. Burning stuff is much cheaper, easier and more effective with matches
2. I purchased a laser from WickedLasers and am extremely happy with it. There seemed to be no basis for the claims in this thread that they are scammers
3. Look it up. Basically anything other than laser 'pointers' (a few mW) are not allowed in most states. It might be confiscated in customs, and you'll get a warning letter
4. Laser safety glasses
5. Don't know, but if there was everyone would be doing it :)
6. Depends on just what you've got in mind for your skirmish game. You can point them towards each other and make Star Wars type noises, I guess.
So what kind of 'scope have you got?

I was fortunate enough to google a company, techlasers (http://www.techlasers.com), that sells them cheap...well, relatively cheaper than any other dealer that was mentioned on this thread.
I took advantage on one of their promos, so I also got safety goggles with my laser, a 75mW green laser pointer. (Safety goggles are a must for anything higher than 15mW) And it was a good buy-one take one kind of deal. Shipping was also fast since they use UPS, it just took 3 days for my order to arrive. :thumbsup:
If anybody knows any other company that's cheaper please let me know as I'm saving up for another one to give to my girlfriend. ;)

Wow, after reading all this fine information I decided to have a look at my Laser Collimator to see what power it emits.
On the sticker it said <5mw.
Now, for me, Victorian Law applies, so I decided to try and find a bit more information on what made an illegal laser.
I found this article http://www.consumer.vic.gov.au/CA256902000FE154/Lookup/CAV_Publications_Product_Safety/$file/laserpointers.pdf which has some very informative information.
The sticker on the Laser Collimator states that it's a Class 3A product. :scared:
I guess I'll think about handing in my prohibited weapon.:rofl: Or forget I ever owned one......
What I have to find out now is if I have a "Lawful Excuse" as mentioned in the Control of Weapons Act 1990.

06-02-2008, 11:50 PM
A description of astronomical purposes (using as a finder mounted on telescopes or hand holding to point out objects in the sky to others) may be considered sufficient reason to grant an approval to possess a prohibited weapon. I'm sure a background check is done. Membership of an astronomical club or association can only help your application. Demonstrating that you understand the potential danger of the beam or its reflections to peoples eyes and that it should not be shone at aircraft, cars etc. can also help.

I need a 250mw laser pointer to mount on my 5 1/2" refractor because they are easier than my straight through finder = I want to try and pop street lights and burn ants and spiders
I need a 250mw laser pointer for my 10" SCT because the angle of the finder at zenith hurts my neck = I'll teach that cat from over the fence to crap in my yard.

Yeah, the tag on my collimator says its a class IIIa as well, with a maximum output of <5 MW.
However, I seriously doubt that it was even greater than 1MW, as I have a few 1MW kicking around and it was absolutely no brighter than any of them. And in any event I replaced it with a 1MW, with a better focused beam, that cost me less than $6. And I also get a few cool picture lenses too!

Beat this for value!
200MW for $29.
But read they safety warnings first! These suckers emit visable and invisable IR light, which may diverge and reflect at different directions.
AND IF THE INVISABLE IR IS REFLECTED BACK IN TO YOUR EYES YOU WILL NOT BE ABLE TO SEE IT UNTIL IT HAS TOASTED YOUR RETINA!

The more I think about these things the more worried I get.

I was tempted by a higher power laser but decided I had no real basis for getting one besides tech-lust.
The IR factor is scary, I thought the visible light on its own was powerful enough to blind you but if you can't even see part of the emitted light it's even worse.
Sketchy.

Why didn't they just confiscate it on the spot?

If the laser is over 3mW it is a prohibited import.
You will be very lucky if it gets past Customs.:shrug::doh:
Lasers greater that 1mW are not allowed in NSW without a dangerous goods permit.
I intend to apply for a DGP soon and will keep you posted.
