Hey guys, this is my first attempt to build a "powerful" laser. The diode is a Nichia NUBM4B 4.7w, bought from techhood on Ebay. I m using a skyray led torch for the housing. Really spacious for a newbie like me to work!
I m using an Astral superdrive V as a driver at 3.6A and G2 lenses. I machined a piece of aluminium on a lathe to use as support and heatsink.
I m also using MX4 thermal paste for better conductivity between diode module and the heatsink. To manage the current i bought a pololu 2808 circuit that handles it, so i can use the tiny switch of the torch itself!
The inner of the laser is not the most beautiful but for first, i liked it!
I want your thoughts about the beam. I think it s not as tight as i would like to. Can you please guide me on how to fix this?
