ABSTRACT:
An excitation system for a gas laser featuring a multiplicity of gain channels uses a resonant cavity to provide broad band RF power division and impedance matching to the multiplicity of gain channels. Integral anode and grid resonant tank circuits featuring positive feedback may be employed to provide a self-excited power oscillator having a very high power capability with good efficiency at low cost. A smaller and higher frequency multi-channel excitation system fabricated from stripline resonator elements may be used for driving small scale multi-channel lasers. A common optical extraction system features either a stable, an unstable, or a hybrid optical cavity mode, with phase-locked or non-phase locked output performance, achieved via external or self-injection.
