HIGH-FREQUENCY DISCHARGE EXCITED GAS LASER Russian patent published in 2011 - IPC H01S3/36 H01S3/38 

FIELD: physics.

SUBSTANCE: transverse pumped gas laser has a housing, an optical resonator, an electrode connected to a resonance-tuned high-frequency power supply, a cooling heat exchanger and a centrifugal compressor. The housing is formed by an outer cylindrical metal casing and an inner cylindrical dielectric casing placed eccentrically inside the said outer casing, hermetically joined to front flanges and forming a gas-dynamic channel for circulating the active medium. The centrifugal compressor creates a stream of gaseous medium which envelopes the inner cylindrical dielectric casing. The section of the gas-dynamic channel with the narrowest cross section forms a plasma chamber and has a symmetrical or asymmetrical profile which varies on the height and has an arc-like or flat shape with angular opening in the direction of flow of the active medium along the width of the zone of the optical resonator. The electrode adjoins the outer surface of the inner cylindrical dielectric casing with its surface. The inner surface of the outer cylindrical casing on the said section of the gas-dynamic channel is insulated from the gas stream and the plasma by a dielectric layer, and the outer cylindrical metal casing is earthed.

EFFECT: high efficiency, power, compactness and light weight, mechanical stability and easy manufacturing and use.
