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

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

SUBSTANCE: laser contains combustion chamber with sprayer block, made in form of pipe coaxial with combustion chamber. Laser also contains sources of gas-like fuel, oxidizer and ballast component, connected by pipelines, including stabilizing branch pipes with sprayer block, also, at output of stabilizing branch pipe of pipeline, connecting source of gas-like fuel to sprayer block, additional gas duct is mounted. Aforementioned gas duct is positioned inside the pipe of sprayer lock coaxially to it and is provided with sprayer head with apertures, mounted on its end, directed towards combustion chamber. Also, additional gas line is mounted with possible movement along the axis of sprayer block pipe. Also, diameter of aperture "d" of sprayer head is connected to internal diameter "D" of sprayer block by relation 0,045≤d/D≤0,08, and distance "x" from sprayer head to the end of pipe of sprayer block, adjacent to combustion chamber is encased in limits D≤x≤5D.

EFFECT: increased specific energy output and reliability.
