    High Current Test Load Question

    Hi, I wanted to ask someone for help on how to build a high current test load. It seems like many of the test loads we have for red and bluray tend to get hot when running above 1 amp. Is it possible to build a test load capable of handling up to a couple amps continuously without overheating...

    My jayrob 18650 445nm Laser

    Hey, I just wanted to post a few pictures of my new 445nm build. I used a jayrob DIY green 18650 host with a copper heatsink and microboost drive. The current is around 1000mA, and the output was measured to be 1.1 Watts. I'm very happy with this build and thanks to jayrob for making such an...

    Thinking of building my first red

    I was thinking of building my first red laser using an LPC815 diode in a pen-style host, but I had a few questions before I order parts. What current should I run it at? I've read about people who got their laser up to 300mW after a glass lens. What current would I need to do this and is it...

    CNI Module Slipped Out of Casing

    I've been having a problem with my CNI green laser recently in that the laser module came loose from the housing. The laser itself still works, but I was wondering if any of you guys know what I need to use to glue it back.  Right now, I'm using tape to hold the module in place, but I think the...

    Dead Blue Ray Diode?

    Hey, I was trying out my first build and I think I killed my diode. It was actually lasing initially, but then I desoldered it because the driver wasn't aligned straight so the back of the aixiz module wouldn't screw in. After I realigned it, it stopped working. How sensitive is the diode to...

    How to protect LD (first build)

    Hey, I was wondering if there were any precautions I need to take to protect the laser diode from ESD and heat during installation. Do I simply use the back of the aixiz module to press the diode into the top? And is 139mA too much current for the P803T diode if I have a heatsink? I've read that...

    Infiniti 125 arrived.

    I've just recieved my infiniti 125 from techlasers, and it seems that I actually recieved a good unit. The laser has excellent divergence, and it's slightly brighter than my 140mw fusion (laserchecked), though there's no way to confirm output until I get it tested. If anyone has any doubts as to...
