PURPOSE:To realize the high oscillation efficiency of a gas laser oscillator by specifying the ratio of inner diameter of a discharge tube to the radial thickness. CONSTITUTION:When the inner diameter of a discharge tube 1 is (d), and the radial thicknesses is (t), d/t is set in the range of 9/1-9/2. Thereby, discharge concentration in a discharge space 5 in the discharge tube 1 can be restrained, and a gas laser oscillator exhibiting the best laser output efficiency can be obtained. By this constitution, electric power is reduced, and excellent working performance can be obtained. |
