Just to add, we have a 35W CO2 laser cutter, and usually light is simply reflected when encountering metal, defeating efforts to cut.

The pipe cutting is most impressive:

Kern Lasers offers a pipe cutting laser system capable of cutting up to 5" diameter steel pipes. A 150W and

400W version are available. The 150W will cut up to 0.080" walls and the 400W will cut up to 1/8" walls. Knock outs, end profiles and joint cutting are just a few of the projects this machine is capable of performing. Take it one step further and etch serial numbers around the pipe before it is cut.

The nice thing about laser cutting is the lack of distortion in the cuts. I think the only other way to get the same result is with EDM machining, but this is much slower.

YOU would need a Q-switched ND:Yag laser to even try this. A Carbon Dioxide laser would just crack the glass from adsorption. Three mechanical things are going to happen when you try this.

  1. The shorting wire IS going to slowy vaporize and fill the tube with a fine black metal powder.

  1. The wire your cutting will outgas.

  2. The Dumet or Alloy 51 wire that passes thru the glass will heat up to red hot and crack the glass.

I've used lasers to heat objects in vacuum before. I know of what I speak.
