GAS DYNAMIC LASER Russian patent published in 1996 - IPC

FIELD: quantum electronics. SUBSTANCE: gas dynamic laser has nozzle apparatus, optical resonator and super sonic diffuser, regeneration heat exchangers for pre-heating working body and extracting heat from used working body, regeneration heat exchangers for re-heating working body till achieving working temperature, distributing devices for cyclical switching of heat exchangers, compressor and cooling system. Device is also provided with recuperation evaporator, recuperation heat exchangers mounted inside cases of pre-heating recuperation heat exchangers, and distribution unit. Input of the latter is connected with output of compressor. Liquid compressor is used in the device. Input of cooling agent circuit of recuperation evaporator is connected with one input of distribution unit mentioned above. Output of the circuit is connected with input of distribution unit of pre- heating heat exchangers. Input of heat-transfer agent circuit of recuperation evaporator is connected with output. Output of the circuit is connected with input of cooling system of the unit. Each input of circuits of cooling agent of recuperation heat exchangers is connected with one of outputs of described distribution unit. Outputs of the circuits are connected with input of distribution unit of pre-heating heat exchangers. Circuits of heat-transfer agent of recuperation heat exchangers have to circuits of pre-heating regeneration heat exchangers simultaneously. EFFECT: improved efficiency; advanced weight-dimension characteristics of lasers. 2 dwg
