METHOD TO STABILISE VOLUME CHARGE IN HF/DF PULSE-PERIODIC CHEMICAL LASER Russian patent published in 2012 - IPC H01S3/38 H01S3/95 

FIELD: electricity.

SUBSTANCE: method includes supply of pulse voltage to barrier electrodes joined with metal electrodes. Pulse voltage is supplied at current density of volume phase of discharge of at least 1 kA/cm² to barrier electrodes, having semiconductor properties, combining active and capacitance resistances. Active resistance is determined by volume resistance of barrier electrode material equal to 48 - 52 Ohm·cm, and capacitance resistance is determined by the value of relative dielectric permeability of barrier electrode material equal to 1800 - 2200.

EFFECT: higher specified characteristics of radiation energy.
