Re: absorbing all that nasty coherent energy from a cutting laser ...

I don't know what they do in real life, but what about using a tank
filled with a liquid dye absorptive at the lasing frequency and
recirculate it through a heat exchanger, or 

Expand the beam with high powered optics to the point where the power
density is not all that high, use a water cooled solid absorptive
target.

 just more half-baked ideas ..
