This alteration will work for the following model which is from ebay:

If you would like to tweak the 1mW green laser pointer listed above for a brighter beam, this is how to do it:
with the battery case removed you will see the spring at the end of the module housing
carefully remove the black foam spacer and place to one side
push down on the momentary switch button untill it slips under the case and gently push it past the pc board and spring until it falls out (you may have to gently lever the pc board down to allow the button to slip past)
the switch fixed to the pc board should now be exposed
using a pair of needle nose pliers, secure the spring and pc board, now gently turn the assembly anti-clockwise
with the pc board and diode free, remove the assembly and locate the small pot with a small phillips head socket
turn this pot anti-clockwise using a small screw driver and put the whole assembly back together in reverse order
I turned my pot all the way anti-clockwise to maximise the output. If turning yours anti-clockwise ends up providing no power to the diode, you will have to turn it all the way clockwise. The 5000 hr laser diode life will be shortened but as they only cost $10, it does not really matter.
If all goes well you should have a brighter beam. If it all goes pear shaped, it won't cost much to replace the whole thing.
The last photo shows the portion of the module that holds the collimating lens. It has been glued to the laser host case. Luckily there is no need to remove it for this improvement.
NOTE: Various models of laser pointers may be assembled using slightly different methods and will need a different approach to remove the module. Anyone who decides to modify their laser pointers will run the risk of damage beyond repair.
