摘要： A tunable optical cavity for use with a chemical laser of the type utilizing a supersonic jet flow of a vibrationally excited gas as a lasing medium and further characterized by having a variable optically active dimension running transverse to the longitudinal axis of its optically active region. The tunable optical cavity is defined by a first laser mirror fixedly positioned on one side of the gas flow and characterized by having an optically flat mirror surface oriented parallel to the direction of the gas flow and a second laser mirror rotatably positioned on the other side of the gas flow and characterized by having a spherical shaped mirror surface oppositely disposed from the flat mirror surface.
