SLIT TYPE GAS LASER Russian patent published in 2006 - IPC H04S3/00 

FIELD: quantum electronics, possible use for engineering technological slit type gas lasers.

SUBSTANCE: slit type gas laser has hermetic chamber, a pair of metallic electrodes, alternating voltage source, a pair of dielectric barriers, and an optical resonator. Chamber is filled with active gas substance. Metallic electrodes are mounted within aforementioned chamber, each of them has surface, directed to face surface of another electrode. Source of alternating voltage is connected to aforementioned electrodes for feeding excitation voltage to them. Dielectric barriers are positioned between metallic electrodes, so that surfaces of these barriers directed to each other form slit discharge gap for forming of barrier discharge in gas substance.

EFFECT: possible construction of slit type gas laser, excited by barrier discharge, dielectric barriers being made specifically to improve heat drain from active substance of laser, decrease voltage fall on these dielectric barriers, provide possible increase of electrodes area, improve efficiency of laser radiation generation, increase output power of laser, improve mode composition of its output signal.
