The bigger one is claimed to be able to burn things. It has a small black piece at the end, when you take the big, spikey silver attachment off, that seems to focus it a bit. It just puts out a big green blob when you take it off. How do you focus it to get hot? Or can that even really be done...

Thanks for the advice. Any other suggestions on the id of these 2?

Need help identifying these pretty generic lasers. Bought both off Craigslist. Both are green 532nm. The smaller one is advertised as 50mw (probably closer to 5mw) The bigger one is advertised as 300mw (probably closer to 30mw) What fun can I have with them, etc.? Thanks.
