    Abstract: A series of fences are placed across the side walls of a flow channel forming the optical cavity of a gas dynamic laser which contains the gas dynamic laser flow therein and are positioned between end walls containing the laser beam mirrors and apertures. The fences are positioned lengthwise with the direction of flow and are located on each side wall of the optical cavity. They are spaced so that they will absorb and/or reflect all rays intersecting the optical cavity side walls at a grazing incidence. The invention herein described was made in the course of or under a contract with the Air Force.

    Abstract: The device includes a closed cycle gas dynamic laser wherein the lasing fluid is recirculated in a closed loop. The closed loop includes a nozzle array, a lasing cavity and a diffuser. The exit of the diffuser is connected to the inlet to the nozzle array with a fuel heat exchanger located in the lasing flow and a pumping means located between the heat exchanger and the nozzle array. To provide for cooling of the pumping means and to improve diffuser performance, gas bled from the diffuser is cooled by two heat exchangers and pumped into cooling passages in the pumping means. The heat exchangers for cooling the flow to the pumping means are located in series and carry fuel from a supply to an injector in said combustor and the heat exchanger in the lasing flow cools the fluid and carries the fuel from a supply to an injector in said combustor.
