Resonant cavity techniques have been used to implement a high power source of radio frequency excitation for many parallel laser elements in a simple, compact, and low cost structure. A triode oscillator was designed capable of driving up to 48 independent and dynamic loads by utilizing the unique nature of a resonant cavity to extract multiple outputs via magnetic coupling. Over 25 kW of power has been generated at 80 MHz while driving 8 independent CO2laser slab geometry gas discharges. ©1996 American Institute of Physics.
