Gas laser apparatus

Patent ·
OSTI ID:5780851
A gas laser apparatus having an anode and a cathode for imparting a glow discharge to a stream of laser gas in response to a high d.c. voltage, also includes a dielectric electrode positioned within said stream of laser gas between the anode and cathode for exciting a pulsed silent discharge of the laser gas in response to an a.c. high voltage power source that supplies a pulsed high a.c. voltage to said dielectric electrode. A pulsed large-current glow discharge is produced between the anode and cathode to thereby emit a large, pulsed laser output. The apparatus may also include controls for controlling the power of the silent discharge excited by the dielectric electrode to thereby control the laser output.
