When I say professional, I mean the type you see on high power hand-helds from places like CNI and Laserglow. Like these - http://www.cnilaser.com/PDF/PGL-III_-C_-532.pdf Laserglow Technologies - Handheld Lasers, Alignment Lasers and Lab / OEM Lasers Hulk Ultra Series 350mW Green Handheld...

This is one of the Super over specs from swim's pen shop. I was great until I put it in my pocket for a while and now the beam in very messed up. Here is the un-colaminated light. Anyone have any idea what's wrong? I don't have another too compare it to. Also this was taken with decently...

I finished my PHR build, but I can't seem to get it to light a match, Its driven at 130ma and even when I focus it to a tiny dot with a 405-G-1 lens it doesnt light it. I can feel a bit a heat on the back of my hand, but not that much. Any advice on how I burn this match? I am afraid I hurt...

I am going to embark on building my first 445nm and am deciding on what batteries + host to use. I kinda want to use mohgasm's linear driver @ 1.62A with two 3000 Mah 18650's, But was wondering what type of battery life I would get with that. also, would I get exactly half that with 1500 Mah...

I am building a DDL driver and when I went to test the voltage over the 1ohm resistor, I only got 11.7mV and if I changed the pot, nothing would happen. At first it I though it was the pot's fault, so I de-soldered it and flipped it around, then I tried a new one, but still have the same...

I have gathered materials for my driver and am now looking to buy my diode, Aixiz module, lens, and battery. I realize a standard 9v would work fine but would like to go with something with a bit more lasting power. All I see on most shops is 3.7V batteries or 4.2. With 4.2 X 2 I could get...

I though I might as well build my own driver for my first build, so I went out and bought the required parts today. My local electronics parts shop did not have the 1N4001 diodes that are used in this link,Laser driver - It can be done so I bought some 1N4004 diodes as they were the closest...
