Lateral mode excitation type gas laser device

Abstract

Abstract PURPOSE:To greatly increase the maximum output power of main discharge, and attain the high power output of laser resulting in the realization of high efficiency laser oscillation, by remarkably reduce the gas flow turbulence due to a dielectric electrode. CONSTITUTION:A rectifying member 14 is mounted on the cylindrical dielectric electrode 6. Since the gas flow turbulence due to this electrode arrangement is remarkably reduced, the instability of the main discharge due to the gas flow turbulence is prevented, and the maximum output power greatly increases. Under the normal typical laser operating condition, the output power increases approx. twice, and therefore the laser output also increases approx. twice. Simultaneously, the set position for the dielectric electrode particularly in the direction of gas flow can be arbitrarily set. Since the gas flow turbulence is greatly reduced by the streamlined dielectric electrode 15, the high output and high efficiency of the laser and simultaneously the improvement of lateral mode patterns can be realized.
