Hello, I want to build a 1.6W 450nm laser. It's my not first build. Previously had 635nm 350mW build. I'm looking for a reliable circuit for my blue diode. I want to build power supply circuit on my own. I have LiPO batteries, 8.4V or 12.6V. Is there any possible circuit to be built?

Hello, today I built LM317 LD driver. http://www.rog8811.com/LM317%20components01.jpg?0.35312663627278806. Problem is that when I turn on, resistors are on 5 Ohms, voltage between LD+ LD- is almost the same like power supply. Power supply ~7.6V (not fully charged). I added test load, Turned POT...

Hello, I'm again trying to build a red powerful burning laser. Last time I burned 300mW laser with 100mA current when diode was in big heatsink in 2secs. This time I don't want that happen again to me. I have focusable laser host Focusable Laser Module Host/5.6mm Laser Diode Case w/h Lens/DIY...

Hello, I received my red laser diode 660nm 300-350mw CW Re Laser Diode DIY/Lab//TO18 5.6mm | eBay and module host Focusable Laser Module Host/5.6mm Laser Diode Case w/h Lens/DIY Laser Host/1pcs | eBay . I use this LM317 driver...

Hello, I'm little new to lasers, I made few mistakes, so now I don't want to do them anymore. So I want to make red burning laser, I have LD driver with LM317. I want to buy 660nm 300-350mw CW Re Laser Diode DIY/Lab//TO18 5.6mm | eBay this laser diode, but will this laser burn things without...
