Hmm, well, these guys actually made their own laser tubes, but the guy who
demoed the equipment was not the laser guy, but the computer and motion
control guy, so he may not have given the correct info. I'm pretty sure there
was only one tank, and I thought it was pure CO2, but maybe it said something
like "Laser CO2" or something. Only 5 - 8% of the CO2 - interesting!
This was a number of years ago, too, so my memory may be fading.
