UNSTABLE MULTIPASS RESONATOR OF SUPERSONIC CHEMICAL OXYGEN-WATER LASER

摘要

FIELD: laser engineering; miscellaneous supersonic chemical oxygen-iodine lasers.;SUBSTANCE: proposed resonator has two focused mirrors, even number of intermediate mirrors, and active medium characterized in improved energy take-off. Active medium is disposed between flat intermediate mirrors. Input mirror is concave and output one is convex. Size of intermediate mirrors is a multiple of aperture size.;EFFECT: enhanced energy efficiency and emission intensity; enhanced gain and its uniformity in active medium and output aperture at low response of resonator to malfunctions.;3 cl, 3 dwg
