APPARATUS FOR EXCITING SPATIAL CHARGE IN DENSE GASES Russian patent published in 2014 - IPC H01S3/97 H01S3/38 

FIELD: physics.

SUBSTANCE: invention relates to quantum electronics and can be used to excite active media of gas lasers. The apparatus for exciting spatial charge in dense gases includes a high-voltage source connected to elongated, blade-shaped corona and current-collecting electrodes mounted along a dielectric cylinder which is capable of rotating. An electroconductive screen and a dielectric film are placed on the outer surface of the cylinder, wherein the corona electrode is placed along the radius of the cylinder with spacing from the cylinder. The screen is in form of two or more sections extending along the cylinder and electrically insulated from each other, wherein the section passing through the zone of the blade-shaped corona electrode is connected by a sliding contact to the grounded terminal of the source, and the section pass through the zone of the blade-shaped current-conducting electrode is connected by a sliding contact to the potential terminal of the source. Potential applied to a section of the screen can be controlled, for example, by a potentiometer.

EFFECT: increasing discharge power.
