I just built a 1W 808nm IR laser. It works really well and burns nicely but only at about 5cm. No matter what distance I put the lens at it's focused only to one point. :confused:
I tried 3 different lenses that I had but they all do the same thing. I've built a green, red and violet laser...
I have a 300mw 808nm laser diode w/driver and this lens:

I looked at vids and pics and everyone has a pinkish dot but I have a dim red dot. do I need a special lens or something to...
I bought a brand new laser diode:

and put it together with a new driver:

but when I hooked it all up the diode seemed really dim. I have to put it like 1inch away from something to...
Ok, so I put together a green laser using
532nm 100mw Green Laser Diode Module DIY/Lab/Industrial | eBay
and 1 14500 lithum ion battery to power it up.
it says 100mw with 10% tolerance so that means it's ganna be lower, but it's unable to burn anything at all. I can kinda see the beam inside...
I have a 405nm 250mw laser diode (at least that's what the title said when I bought it). I put it together with this driver.
405nm 100-300mw Laser Diode Driver Reverse protection | eBay
I'm using 2AAA batteries to power it up.
I was wondering what would be an ideal current for burning and long...
Hey everyone. This is my first post on this site :yh:
I'm new with lasers and I'm still trying to figure most things out. I bought a 405nm 250mw laser diode and hooked it up.
