DEVICE FOR EXCITING ATMOSPHERIC-PRESSURE DISCHARGE IN GAS LASER Russian patent published in 2002 - IPC

FIELD: quantum electronics; pulsed atmospheric- pressure gas lasers. SUBSTANCE: electrodes are proposed to be shaped so as to ensure that length of their effective Ernest-profile section complied in width with electrode clearance d₀. Electrode sections having rounding radius of 1.3d₀ and width of 0,75d₀ are abutting against mentioned effective section along tangential line on both ends. Peripheral effective sections are joined with preceding ones before rounding electrode at curvature radius of 0,3d₀. Rear surface abutting against peripheral effective section of electrode has curvature radius of 0,1d₀. Effective section of electrodes may be provided with hollow area covered with metal net. EFFECT: enhanced effectiveness of power input in discharge space, enhanced laser efficiency, simplified shape of discharge electrodes. 2 cl, 2 dwg
