You also did not think about the date of the last post & the OP--4/2011.
When people who know nothing about lasers see ANY burning by laser it only makes them more sure that lasers have no practical use and maybe making them illegal to own is a good idea. Most vets here are 'burned out' on burning by laser a LONG time ago. When I do that it is ONLY just to show how dangerous these can be and I am careful with who I show. Many newcomers here at LPF seem to be almost obsessed with this..
My comment about necroposting was NOT meant to be taken in a way that makes you shy from posting in the future--sorry. +3 (apology)
btw I never spell anything wrong it the fault of my stupid fingers and my keyboard--lol
Ha! I have never even heard the term necroposting!
Maybe this will help me. I'm going to check the date from now on!
Nice collection by the way. that 1.3w green must be impressive.
Turns out the peep hole lenses are crap, very messy. Im going to try some tiny binocular lenses I have. I was planning to expand the beam into a fatter less hot beam.
I am also somewhat bored of burning things.
Look at here, if u want to really extend it's burning power u must use large collimator, that will focus your beam to the object. OR just reduce divergence, but it will be not good method because your laser has big divergence. look at your DPSS laser, i mean how it produce laser light...
