Wave guide type gas laser device

Abstract

Abstract PURPOSE:To obtain a laser device with its output not reduced by temperature rise in the laser gas by a method wherein a pair of electrodes of specified material is provided along the laser beam axis, the laser beam incoming end is covered with insulating material, and a cover is applied for the formation of the inside into a wave guide. CONSTITUTION:A pair of electrodes 41 composed exemplifiedly of Cu or Al with excellent thermal and electric conductivity are optically polished and arranged longitudinally along the beam axis 42 with some distance between the two electrodes 41. Also attached between the electrodes 41 along the beam axis 42 and near an end of the electrodes, is insulating material 43 with excellent conductivity and insulating property made exemplifiedly of BeO, BN, SiO, or Al2O3, which is enclosed in a cover 45 for the formation of a wave guide 44 inside. A mixture of three gases, CO2, N2, and He, is enclosed inside the cover 45, and a three value logic type high tension pulse voltage is applied across the electrodes 41, which causes a laser beam to be emitted along the axis 42 after reflection upon a reflector not illustrated. Proper choice of material realizes a device enjoying excellent features of RF excitation.
