ELECTRIC-DISCHARGE MULTIPLE-TUBE LASER WITH DIFFUSION COOLING OF GAS MIX Russian patent published in 1997 - IPC

FIELD: laser equipment. SUBSTANCE: gas-discharge tubes in packet are arranged around circle with equal spaces. Planes of bisectors of angles of intersection of mirrors in angular mirror prisms are displaced with respect to each other around circle center by angle of π/n, where n is number of gas-discharge tubes in circle. This results in transmission of laser beams through all tubes starting from one which is located in opposite to hinder blind mirror and ending with tube which is located at opposite end of circle diameter. Hinder blind mirror is located at end of gas-discharge tube in parallel to its axis. EFFECT: increased functional capabilities. 4 cl, 6 dwg
