GAS LASER Russian patent published in 1995 - IPC

FIELD: physics. SUBSTANCE: gas laser has extended cathode, anode and auxiliary electrode. Dielectric chamber with slot is positioned along working surface of cathode. Igniter is put close to auxiliary electrode on edge of chamber. Chamber communicates with circuit of pumping through of working mixture so that butt on side of igniter is connected to circuit of pumping-through in section after fan and the other butt - ahead of fan. All electrodes are connected to D.C. source. Periodic transfer of pre-ionization plasma along working surface of cathode occurs thanks to difference of pressure in chamber ensuring pulse-periodic mode of operation of laser. EFFECT: ensured authenticity of pulse-periodic operation of laser. 3 dwg
