What definits co2 laser output power ? length of the tube ? If I used more voltage than I should will the tube explode or just be more powerful ??

I'm not 100% sure on this, but I believe it is the length of the tube, and the bigger tubes require higher voltage, and slightly higher current.

Power of a co2 laser is pretty much independent of the bore diameter, as a larger bore will allow more gas to be excited, however will mean there's a longer path for the gas molecules to reach the laser wall and be cooled back to the ground state, so they can be pumped up again and lase. A more powerful tube will be longer, a good longitudinally excited laser can reach about 4050 watts per metre.

Narrow body tubes can reach 100 watts per meter, fatbody tubes can reach <140 watts per meter. It depends on a LOT of variables, tube diameter, gas composition, electrode conductivity, amperage supplied, voltage supplied, quality of output coupler, quality of tube reflective mirror, tube mean temperature, mirror temperature, lens temperature abberation, lens material, spherical abberation and a few other things.

From there you go to GSI shell (enclosed DC glass tubes) series that go to 600 watts (but cost more than the average house) for example the last GSI TX 200 I bought was $24,460 + VAT for the tube alone. cheers Dave
