Most of the commercial desktop style laser cutters seem to start at about 30 or 40W CO2.

There's lots on the net about using solid state diodes from laser pointers or DVD burners, but these have barely enough power to cut paper. Black paper OK. White paper nope.

I found this a while ago - the guy has built a couple of machines using CO2 tubes.
