GAS-DYNAMIC LASER AND METHOD FOR ITS REFINEMENT Russian patent published in 2006 - IPC H01S3/22 

FIELD: quantum electronics, possible use for building powerful laser plant, working on products of combustion.

SUBSTANCE: laser contains source and system for feeding components of working body, gas generator and control system. Also, system for feeding components of working body additionally contains source of ecologically clean admixture and gas generator, connected by feeding pipeline. Also, feeding pipeline is provided with shutoff valve and stabilization branch pipe. Also, circuit for switching on the shutoff valve is functionally connected to system for feeding one of components of working body through control system. Refinement of laser includes feeding components of working body into gas generator, mixing fuel components, igniting combustive mixture, emission of used working body into atmosphere and alteration of laser characteristics. Also, composition of working body includes ecologically clean admixture - tracing substance. Feeding of mixture is performed in a series of launches, combining feeding in series with feeding of each one of main components of working body. At second stage, regular fuel is used. As ecologically clean admixture - carbon dioxide is used, feeding of which in amount 1-3% of volume of total flow of working body is performed when work mode is reached in resonator.

EFFECT: protection of environment by decreasing flow of fuel and expansion of working temperatures range.
