Abstract
An amplitude stabilization circuit for a CO.sub.2 laser employing a filter for generating a Q-switched baseband video pulse representing intracavity laser flux, a comparator to detect when the video pulse and flux reach a selected level, and logic timing circuitry for timing generation of a Q-switch discharge pulse to occur at the peak of the intracavity flux. A second comparator is advantageously used to generate a sample signal for frequency locking from the baseband video pulse.
