Danger Laser

15 01 2009

I just received a Coherent 808nm Laser Diode 3.5V 60-90Amp 50-60W:

Freaking awesome. High power cutting laser. I’ve always wanted one of these.  This is powerful enough to cut just about anything except metal. 

I’m going to turn this into a cutting head for the reprap.

You can see the electrical power connects, and the water cooling connectors.

 

This laser is dangerous:

THERE ARE NO “OOPS THAT WAS BRIGHT” SECOND CHANCES WITH THIS LASER! A single careless glance into the beam or it’s reflection WILL PERMANENTLY BLIND YOU FOREVER! To the eye the scattered output looks as bright as a red laser pointer, but that same “weak looking” beam will light a piece of cardboard on fire in about 1/4 of a second!

Protective eyewear is mandatory. I’ll provide a full safety rundown prior to firing it for the first time.
