I got a cheapo ebay 303 green DPSS here putting out 3 (53x nm) lines. Looks like harmonics. I didnt think a DPSS can do something like that. Though Iv read people say similar things about 589nm spartans. No other 532 i have does anything like this. Pump diode leakage measures 804nm. Any thoughts?

Hi everyone. Here's my 10mw 635nm build made from a red <1mw DX 650 keychain. LD is a 10mw 635 from Rothiner Laser along with a 4.5-6v red laser driver. Original diode was a flat chip. A 5.6 groove had to be drilled out for the new LD. Power source - was modified to take either 2x lithium...

Here my second 445 pointer build. This time custom finished to match the wavelength. Custom made 317 driver set to 300ma. Guesstimated output 125-175mw. Power source 2x 10440's Currently the indicator hole does not light up. I'm working on that. It will either be a indicator or a second...

Ok, so I tested a few in my 445 build. Aixiz acrylic(slightly enlarged aperture. not completely), aixiz glass, aixiz glass 405/445, and 405-G2. Data: acrylic - 52.5 mw aixiz 405 - 47.6 mw aixiz glass - 51.8 mw 405-G-2 - 60.0 mw only the G-2 has the expected result. the rest seem to go...

Here is my second 445 build. :D :D :D Aixiz module in a golden orb heatsink, Aixiz 405 glass lens. I had it shining across the room while I was adjusting the current. There was a burning wood smell a few moments later. Though it came from outside. Didn't notice till after that it was my...

Here's my 445 in a pointer host. Specs: 445 diode running 350ma. 120mw output. 2x 10440 battery. aixiz 405 glass lens. diy 317 driver. Gonna make a labby next.

Does anyone know how to take apart one of these hand held lasers properly. In the one im trying to take apart everything seems to be screwed into the housing but it wont turn because the plastic button is preventing it. How do you remove the button? im afraid to try to pull it out with too much...

I'm trying to build a lm317 driver board that will fit inside of the aixiz module. I'm using SMD parts and I don't think the tiny smd trimpots can handle 200ma+, so i'm going to set up the lm317 as a voltage regulator with a resistor in series with the LD. Still looking for a pot/resistor pair...

I just picked up a 20x Samsung for $30 and pulled its diode in an attempt to fix my pulsar. Iv read that most burners have 2 diodes, 1 for CD and 1 for DVD. This one has both in one package and no photo diode. i don't know if i should call it an open can as it has no can at all. the laser chip...
