    Newbie trying to get a laser diode working

    Hey thanks for the response, I've already looked on eBay and while there are drivers that can do 850nm none of them can do the voltage or current I want, most have a voltage of 3-5 (I'm shooting for 2v) And a max current of around 500mah (I'm shooting for 3a). If you know of one that can do what...

    Newbie trying to get a laser diode working

    Yeah, I already did some research and found out that 850nm is NIR which is basically invisible so I'll be taking proper safety precautions when using it. If I can get to using it. As an update, my plan for powering it so far is a 3.7v 18650 cell as it can provide the current needed and then...

    Newbie trying to get a laser diode working

    Hi, I'm just getting into lasers and recently purchased a laser diode to make a laser to engrave wood with. It was only after I purchased it that I realized that getting it running would be a lot more complex than just hooking the diode up to the specified voltage and amperage. I've done a lot...
