    CO2 lasers and PSU's

    Hey guys, its been a while... So I have a CO2 laser cutting machine, currently using a 1.2m long CO2 tube, apparently rated for 40W. The laser tube has seen the light at the end of the tunnel and is dead. I'm wanting to replace it, but the cheap 40W laser tubes are all 700mm long. A good 500mm...

    WTB: High power 532nm 12mm module.

    What kind of power do you want? 200mW is about the limit you're going to get out of a 12mm module. Typically the 300mW+ modules are in a 22mm package

    Laser Diodes and Gear Best Lasers?

    Looking for someone to repair my 445nm 3.1w sci-fi laser

    Do you have a soldering iron and a multimeter? You could probably fix it your self. Otherwise wait for someone from Florida to come past this thread.

    driver question

    700mA is a safe level for your diode. The LM317 driver will consume some voltage... so you must make sure your supply voltage is atleast 1.5V above the forward voltage value of the diode.
