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 for pumping working medium that incorporates annular set of nozzles, working-medium components supply system, and control system. Set of nozzles is essentially changeable nozzle-simulator assembled of set of at least four rings. These rings are equally spaced apart. Symmetry plane of each space is perpendicular to axis of set of nozzles. These spaces are formed by means of distance pieces installed between rings. Set of nozzles is provided with end-position alarm functionally coupled with system for feeding working-medium components through control system.

EFFECT: reduced cost of laser harnessing.
