    1W IR weird focus.

    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...

    IR 808nm lens/color help.

    I have a 300mw 808nm laser diode w/driver and this lens: 660nm/808nm Glass Collimating Lens/M9P0.5 Metal Frame - eBay (item 260724564678 end time Jun-18-11 05:24:39 PDT) 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...

    Will this driver work with this diode?

    Will this 808nm driver work with a 808nm 1W diode. It says 100mw-500mw so I'm not sure. 808nm 100-500mw Laser Diode Driver Reverse Protection | eBay

    New red laser diode Dim?

    I bought a brand new laser diode: new 150mW 650nm Burning Red Laser Diode profession | eBay and put it together with a new driver: 200mW red laser diode driver /150-350mA adjustable | eBay but when I hooked it all up the diode seemed really dim. I have to put it like 1inch away from something to...

    100mw green laser? + Battery seems to die fast...

    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...

    Ideal Current for Laser

    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...

    405nm laser diode. How Do I Focus Laser?

    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. New 250mW+ 405nm 6X High Power Blue-Violet Laser Diode - eBay (item 280649581262 end time Apr-24-11 04:17:48 PDT) It...
