GAS-DISCHARGE LASER, LASER SYSTEM AND METHOD OF GENERATING RADIATION Russian patent published in 2014 - IPC H01S3/03 

FIELD: physics, optics.

SUBSTANCE: invention relates to laser engineering. The gas-discharge laser includes: a laser chamber (1) consisting a ceramic material and filled with a gas mixture, elongated electrodes (2, 3) defining a discharge region (4), a preionisation unit (5); the gas circulation system (9, 10, 11, 12, 13); a set of capacitors (14) arranged outside the laser chamber (1) and connected to the first and second electrodes (2, 3) via electrical leads (17, 18) of the laser chamber (1) and gas-permeable reverse current leads (19) disposed in the laser chamber on both sides of the electrodes; a power supply connected to the capacitors and a resonator. The laser chamber (1) comprises a ceramic tube (24) and two end flanges (25) rigidly interconnected by a fastening system (26) that extends along the ceramic tube (24). The fastening system (26) is in form of a metal tube encircling the ceramic tube, equipped with a sufficiently wide extended recess for installing the set of capacitors (14) and having on the faces of the end flanges attached to end flanges (25) of the laser chamber (1) or in form of tightening beams.

EFFECT: high power.
