Abstract

Symmetrical edge and face cooling geometries have been evaluated as a thermal control technique for a high power acousto-optic modulator employed as an intracavity mode locker inside a pulsed TE, 0.5 atm, mode-locked CO₂ laser oscillator with a 0.5 - 1 kW average output power. Both cooling methods have proved effective in minimizing transverse thermal gradients generated in a germanium crystal of the acousto-optic modulator operating in the Raman-Nath regime.
