    He-Ne Laser PSU Brick

    I'm looking for a power supply brick for a He-Ne tube, as the one i was using has burnt out. Looked on eBay & found nothing here in the UK, only a couple of complete head/PSU systems in the USA. Anybody know where i can get a PSU? Pref 12v input Thanks in advance Vanguard

    Quick Question: Laser Driver

    Hey everyone, i'm after a laser diode driver that i can use to test virtually any laser diode from a DVD or CD burner, i have tried an LM317 constant current based design, but don't seem to be having any luck with those. Can anyone recommend a circuit that i can build myself?

    IR Collimator

    Hi I have built a 600mW 808nm IR laser, the diode itself is a TO-3 open can type, but a simple laser pointer type lens just collimates the beam to a diverging line, what other optics do i require to correct this?
