Laser optical resonator assembly
Patent
·
OSTI ID:6415691
An optical resonator assembly mounted externally on a hermetically sealed gas transport laser comprises a u-shaped tubular bench secured to the laser housing top wall and having an elongated beam with legs extending at right angles to opposite ends, respectively, of the beam adjacent to the front and rear walls of the laser housing. Flat bases depend from the respective bench legs and overlay optical windows in the front and rear housing walls through which the internally generated laser beam passes. The bases have openings aligned with the windows, respectively, and adjustably mount mirror support plates, respectively, adjacent to those openings. Mirrors attached to the support plates define the laser optical cavity. The bench is a rigid tubular structure providing stable support for the optical components and also constituting a fluid conduit for carrying cooling air to minimize thermally induced dimensional changes.
