GAS LASER WITH INTRARESONATOR RADIATION SCANNING Russian patent published in 1995 - IPC

FIELD: quantum electronics. SUBSTANCE: optical resonator of gas laser is formed by spherical mirror of total reflection and by flat mirror with semi-transparent zone in center located in its focal plane. Working medium is positioned between two flat high-frequency electrodes. One of electrodes on side of interelectrode gas is coated with layer of dielectric with parallel conductive tracks oriented along resonator axis. Tracks are connected through controlling commutation device with negative pole of constant voltage source. Positive pole of this source is coupled to high-frequency electrodes through low-pass filter. EFFECT: reduced dimensions, simplified design, enhanced efficiency. 2 dwg
