GRID SEPARATION OSCILLATOR USING RESONANT COAXIAL CAVITIES FOR HIGH-POWER MULTICHANNEL LASER

Resonant cavity techniques have been used to implement a high power so urce of radio frequency excitation for many parallel laser elements in a simple, compact, and low cost structure. A triode oscillator was de signed capable of driving up to 48 independent and dynamic loads by ut ilizing the unique nature of a resonant cavity to extract multiple out puts via magnetic coupling. Over 25 kW of power has been generated at 80 MHz while driving 8 independent CO2 laser slab geometry gas dischar ges. (C) 1996 American Institute of Physics.
