60W: Glass and 1x4

This is the top to an old decanter. Note: the glass was not cut, it cracked because of heat stress.

It's strange how it'll punch through 1" of wood in less than a second, but won't go through 2" of wood at all.

Nice!!! But can you carve with it?

Similarly to a jigsaw? Only very slowly and with fine motors to more the piece. You're taking about the difference between a 1 dimensional cut and a 2 dimensional cut. Even the slight jerking caused by moving it by hand will cause it to skip over small areas. Perhaps with a smaller diameter.

Damn,
I got to make one of those with a 8 foot light tube and my desiccated breath. I read how to do it long time ago. Easy as: HV circuitry, Vacuum Technology, Glassworking, electronic impedance matching, optical alinement, material procurement and week of good luck and money to burn.!

That laser is money well spent man, bravo!

I read if your beam goes through a 1/2 wave plate or something, it's stops the destructive feedback to the OC. As is (your setup)the beam bounces back with circular polarization.

Want deeper penetration!!! ;D ;D ;D

Awesome!!!! that laser is so sweet! ;D ;D ;D

Max

really awesome! now thats what i have in mind when talking about "burning laser"! nothing with "what match works best?" and "what sharpie is the blackest?"..

i love the near instant hole and smoke through the wood!
