Nothing real special... This is the laser engraver we use to mark the enclosure lids for a product of the company I work for.

It's a Laservall 20W, air-cooled, DPSS Nd:YVO4 laser.

I liked that one. Is that burning the anodizing off aluminum?

since it's DPSS Nd:YVO4, i'm guessing that it's 1064nm? :-? Why not use the 808mn instead? It's more powerfull....

Switch,

808 LD have crappy beam specs. but it makes a great pump sourse. for YAG/YVO crystals
and about 30% output to input power. ;)

I just thaught that 808nm is a shorter wavelength and would be better for engraving, and that the direct output from the pump diode higher.But you;re right,ussually the beam coming out of the crystal is way better especially than the multiwatt multimode 808nm diode ::)

Pretty cool.. but i'm a bit puzzeled about the strange route the laser takes to engrave this - especially when filling out the letters int he end.

:cool: Are you in Memphis or does your company provide those to Comp Cams?

The reason I ask is that I have several friends that work there. ;)

Yeah.. It's pretty ridiculous. I think it's like that because that's how the engraving software traced the original graphic artwork which was pixelized. I've done a couple of others by using vector art as the original image and then exporting to HPGL for import into the engraving software. It works much better.

Trying to get ahold of 20 Watts of 808 with a lens would be almost impossible. Let it drive a crystal and you have a beam which can be focused.

That was really, really cool. I'd never seen one of those in action before.
