ELECTRIC DISCHARGE PULSE PERIODIC GAS LASER Russian patent published in 1994 - IPC

FIELD: laser technology, medical science. SUBSTANCE: electric discharge pulse-periodic gas laser with preionization with ultraviolet radiation has discharge chamber with anode and cathode electrodes, means to form corona discharge containing two electric plates outgoing from longitudinal edges of anode electrode. First part of each plate adjoining anode electrode has shape of arc facing discharge gap with convexity. Second part of plate goes out from first one on side opposite to anode electrode in direction opposite to discharge gap leaving it open on side of longitudinal edges of electrodes. EFFECT: facilitated manufacture, expanded operational capabilities. 3 cl, 1 dwg
