A gas dynamic laser is formed having a combustor with a cylindrical combustion chamber, said combustion chamber is formed having a discharge opening at one end and primary injection means at the other end with a plurality of injector tubes for injecting a combustible mixture into said combustion chamber; an igniter is included for igniting said mixture; a secondary injection means is located adjacent the discharge opening and has a plurality of nozzle tubes for injecting an oxidizer, one nozzle tube being included for each injector tube; each cooperating nozzle tube and injector tube being axially aligned, with said nozzle tubes directing the oxidizer towards the injector tubes, a mixing chamber being located downstream of the secondary injection means for directing the gases to a nozzle array. The secondary injection means is constructed to have easy accessibility to the nozzle tubes.

Combustor for gas dynamic laser

A turret device mounted on a housing is used to project a laser output beam and aim it in elevation and azimuth. The turret device includes a rotatable enclosure having an optical cavity for transmitting a laser beam therethrough and out a cutout to a target. Means are provided to operate the turret in azimuth and elevation. One control moves a turret platform to obtain an azimuth movement of the beam while the other moves a rotatable mirror to obtain an elevation movement of the beam. A laser device directs a laser beam from within a housing through the rotating part of the turret into the enclosure from which it follows the path set forth above.
