Just wanted to get peoples' opinions on this, since I have little experience with greens (and lasers I didn't build myself). I bought a supposedly 5 mW green laser off eBay for about $12. Recently, just for the hell of it, I broke off its metal cap and realized I could adjust the lens nut with a screwdriver. So I focused it to about 8" from the aperture, and discovered, to my delight and slight alarm, that it would ignite flash paper in seconds and smoke black stuff.
This has got to be way over-spec, right? From what I understand, the IR pumping diode has to be fairly powerful..could this thing just lack an adequate IR filter?
