I have a red laser with lm317 driver and would like to try and run it from a solar panel. It is not a very big panel only rated for 4W but on a sunny day it puts out up to 21V. I normally only use this laser with 8.4V max. That is why I didn't want to try using it yet before seeking a bit of...

I would like to know if the following is true. I have a laser using an LM317 based driver. The laser has multiple diodes and driver for each diode. Total current draw is 2A and when the batteries are fully charged they give 8.4V (2 Li-ions in series). Now I have read in a couple of different...

Hey, I have recently been making a few lasers in my shed using diodes from dvd drives and since I'm new to lasers and electronics I wanted to ask a few questions regarding electrical power as well as some specific questions about red laser diodes, sorry if this post is a bit long but I don't...

Hi everyone. I am new to lasers in general and I had a bought a blue laser through someone's private listing on gumtree. It was putting out 1.6W at 445nm. I am fairly sure the diode was rated to 1W and he set the current higher to achieve 1.6W. There is nothing written on the diode and I can't...
