I've had a 75 mw cni laser for two years and recently after taking it apart and lack of knowledge, the diode is no longer working. I know the driver works because i soldered a cheap red diode and it worked. So i figure i broke the ir laser diode from it in the process of taking it apart. So, now i have everything but a working diode for my laser. Any advice on how to proceed from here. I dont want to spend a bunch on a new 75 mw module. Could i upgrade by adding a hd dvd diode to the board? I've read the pages of information and am now ready to rebuild.
