GAS DISCHARGE LASER Russian patent published in 2014 - IPC H01S3/03 

FIELD: electricity.

SUBSTANCE: gas discharge laser comprises the following: a laser chamber filled with a gas mixture, which comprises the first and second long electrodes that are distant from each other, a pre-ionisation unit, a system of gas circulation, a set of capacitors arranged outside the laser chamber and connected to electrodes via electric inputs of the laser chamber and gas permeable reverse current conductors, arranged in the laser chamber at both sides of electrodes, a source of power supply connected to capacitors and designed for their pulse charging to breakthrough voltage, and a resonator for generation of a laser beam. The laser chamber comprises a ceramic pipe with two end flanges rigidly fixed to each other by means of a fastening system stretched along the ceramic pipe. Each of end flanges is sealed with a ceramic pipe by means of a circular gasket placed on the outer surface of the end part of the ceramic pipe. Each end flange has a circular niche on the inner side, where the end of the ceramic pipe is placed, and the end flange closely adjoins the ceramic pipe only on its outer surface in place of installation of a sealing circular gasket.

EFFECT: provision of the possibility to increase capacity of lasers and simplification of their design.
