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

FIELD: electricity.

SUBSTANCE: gas discharge laser comprises: a laser chamber filled with a gas mixture, consisting of ceramic material and comprising the first and second electrodes distant from each other and defining the area of discharge between them, a lengthy pre-ionisation unit and a gas circulation system. The first electrode is located near the inner surface of the laser chamber. The set of capacitors, to which a power supply source is connected, is located outside the laser chamber and is connected with the first and second electrodes via electric inputs of the laser chamber and gas permeable return current leads arranged in the laser chamber at both sides of the electrodes. At the same time the laser chamber comprises a ceramic pipe with two end flanges, which are rigidly connected to each other by means of a lengthy fastening system, and the ceramic pipe of the laser chamber has a lengthy niche at the inner side, where at least the first electrode is installed. Parts of the inner surface of the pipe adjoining the niche form guides of gas flow or spoilers arranged upwards and downwards along the flow from the first electrode.

EFFECT: making it possible to increase capacity of radiation and to reduce losses for production of generation energy.
