FACILITY TO PUMP WIDE-APERTURE GAS LASER OR HIGH-PRESSURE AMPLIFIER

摘要

FIELD: gas electric-discharge laser of superatmospheric pressure with X-ray preionization of active medium. SUBSTANCE: facility to pump wide-aperture gas laser or high-pressure amplifier includes discharge chamber that houses electrodes of pumping discharge: high-voltage cathode and grounded flat anode with grid structure transmitting X-rays, pulse power supply system comprising pulse voltage generator built on circuit of LC oscillator and intermediate capacitive storage circuit which high-voltage plate is connected to cathode and first lead of pulse voltage generator and which other plate is connected to anode and grounded second lead of pulse voltage generator. Facility is fitted with X-ray radiation source-X-ray preionizer bordering on discharge chamber on side of anode. Salient feature of facility consists in that intermediate capacitive storage circuit comes in the form of water-cooled condenser embracing discharge chamber which high-voltage plate is located in water space formed by metal case of discharge chamber and outer shell and is connected through high-voltage lead to first lead of pulse voltage generator and cathode built solid from material with increased photoemission properties and anode displaying rectangular form and having window in the form of grid transparent for radiation from X-ray preionizer made in its central part. EFFECT: enlarged aperture of facility to pump gas laser or amplifier of working pressure of active medium and value of specific energy contribution to pumping discharge. 3 cl, 2 dwg
