You supply RF sealed CO2 tubes with a low-voltage, high-amperage power... figure in the range of 45-50V (SS lasers are usually a few volts, unless placed in series) @ 5-20A (depends on laser power, but these figures are good to about an 80W system).
Excitement frequencies have a fairly wide range, typically from 30-160MHz (+/-).
Your memory from reading is correct. A DC tube needs a sharp voltage spike to begin ionization, which is followed by a more constant lower voltage to continue lasing (fluorescent and HID bulbs work in this manner). An RF tube's gases are excited via radio waves (like a microwave) directly, and therefore don't need to spike to begin ionization... instead, they are given a "trickle" pulse (nothing more than a low duty cycle), which keeps the gas "on the edge of its seat" if you will, waiting for a full turn-on signal.
