First "Build"

Hey LPF,

I've been searching and reading quite a lot today and have decided that I want to build a 445nm laser as my first build. I own a few lasers ranging from 100-500mw currently so this will be a large leap forward, but I think I have been working with lasers long enough to know about high-power lasers' dangers. I already own a pair of safety glasses that cover 445nm so all I am asking of you guys is a confirmation of my build.
I'm hoping to order a JAD kit and options.
Here are my preferred options:
Output: 1.62A
Heat Sink: Copper
Focus Adapter: Plain Aluminum
GITD Mod: Blue
Copper Module: 5.6mm

I would like to know if it's safe to swing for 1.8A with the heatsinking and such. It's not a huge deal but it would be nice to squeeze a little more power out of it.

And lastly I'm looking to get this module from DTR: 2W 445nm M140 Blue Laser Diode | eBay

I believe I have all the tools I'll need except for something to press the diode into the module with. If anybody can give me a way to do that then I'm all set!

Thanks, Kyle

Most people run their m140's on 1.8 amps, so that will be fine. I would just get the diode already pressed into a copper module with a glass or g2 len from here https://sites.google.com/site/dtrlpf/home/diodes/445-m140-didoes

Have a good one :beer:

diode press can be bought HERE

but id get it pressed already with leads for your first build. its easy to kill a diode so take it step by step at first

Ohh that looks good. So I would buy the module with just a diode in it since the JAD kit comes with a driver already right?

Also, will there be any difference between the 3-element or the G-2 besides the end power result?

Thanks, Kyle

They give slightly different dot characteristics but there have been many reviews on that here on the forum. Yes all you need is the diode and module if you have a JAD (Just Add Diode) kit
