Hello all, It's been quite a while since I've posted here. Anyway, I am trying to decide between a 1.1W 450nm from Fast Tech (it's advertised as being b/w 1W and 2W, but a YouTube video I found showed it reaching 1.1W), or a 100+ mW green laser. I have no intention of using this to burn stuff...

Hello guys, I have had a problem in the past with green laser diodes, they don't work in the cold. I've had a few cheap ones in the past, that once they are exposed to the cold, the beam output drops. I have a 50mW diode on the way. I don't know if the driver is made to be ACC or APC. In...

Hey guys, a little while ago, I burned out a green laser diode that I had. I screwed the housing apart, and saw the various components; the piece with the IR diode itself, the expanding lens, and the focusing lens. Now the only thing I could imagine that went wrong is the diode itself. So I...

Hey guys, I bought a 100mW green laser diode (no driver) from some no name company from china. The specs recommended driving it at 250mA. So I plugged it into my variable power supply, and slowly increased the voltage until the supply was delivering 250mA. It worked very well, a nice well...

Hello guys, I'm new to these forums. I built a laser a few days ago using an LPC 826 in an aixiz module from hightechdealz.com. I made the DDL driver circuit to test it out, and it was working okay. I hate using a breadboard to do testing, so I decided to use a professional current source to...
