I guess this is the "fun" part of laser building...

Yes, I used proper ESD procedures, soldering joints were fine and I got HighTechDealZ - High Tech DealZ to solder the LD leads on which are fine. No I didn't use a capacitor - but shouldn't it at least give off a glow?

Hi all I bought a PHR-803T laser diode in aixiz module from HighTechDealZ - High Tech DealZ and it arrived today, I connected it to a simplified DDL driver with just an LM317T and a 12 ohm resistor between ADJ and V-OUT pins. I then connected it to a 9V alkaline battery and nothing. Have I...

Any one sure on the driver setup?

Hi there I am building a 405nm laser (PHR-803T). I want to run it off a 9V battery so I will need a driver. I was going to build a simplified version of a DDL driver with just a LM317 and a 12 ohm 1W resistor between ADJ and VOUT pins of LM317. This would achieve around 100mA-110mA which I...
