GAS-DYNAMIC LASER Russian patent published in 2006 - IPC H01S3/22 

FIELD: quantum electronics; large laser units burning combustion products.

SUBSTANCE: proposed laser has gas-dynamic channel with inlet regulating pipes, control system, sources of working-medium components with shutoff valves, and regenerative heat exchangers. Shutoff valve closing and opening circuits are connected to control system; regenerative heat exchangers are disposed between sources of working-medium main components and regulating pipes. In addition, each source of working-medium main components mounts at least three parallel-connected shut-off valves, each provided with at least four time relays incorporating closing, opening, and output circuits. Closing circuit of first relay is connected to control circuit and its output, to closing circuit of second relay. Output of the latter is connected to opening circuit of shutoff valve and to closing circuit of third relay. Output of the latter is connected to closing circuit of fourth relay whose output is connected to opening circuit of shutoff valve.

EFFECT: enhanced reliability, simplified design.
