DISCHARGE SYSTEM OF HIGH-EFFICIENCY GAS LASER Russian patent published in 2015 - IPC H01S3/977 

FIELD: physics, optics.

SUBSTANCE: invention relates to laser engineering. The discharge system of a high-efficiency gas laser includes, arranged in the housing of the laser, extended first and second electrodes which define a discharge area in between. On the side of one of the electrodes there is a UV preioniser, which is in the form of a system for igniting a uniform creeping discharge between the extended ignitor electrode and an additional electrode, placed on the surface of a dielectric layer which covers an extended metal substrate connected to the additional electrode. The dielectric layer is in the form of a straight thin-wall dielectric tube with a longitudinal section. The ignitor electrode and the additional electrode are placed on the outer surface of the dielectric tube along the tube, and the metal substrate is placed inside the dielectric tube such that at least part of the surface of the metal substrate is superimposed with the extended part of the inner surface of the dielectric tube. The additional electrode is connected to the metal substrate through the longitudinal section of the dielectric tube.

EFFECT: increasing generation energy and average radiation power of the gas laser and simple design of the gas laser.
