3/8" ply is going to be harder to cut with a small CO2 laser. There
is something about ply, I guess the alternating layers or the glue
layer. Probably will need 30-50 watts and a good supply of dry air
or even perhaps nitrogen.

The emmission technologies website was a good suggestion. Certainly
the cheapest (non-ebay) place where you can buy kits or sealed
tubes. Don't forget the vacuum pump, gas cylinder, regulator, and
flow valves when you start thinking about building a flowing gas
laser to save money.
