Abstract

PURPOSE:To increase the output of a gas laser device by providing a rectifier in the vicinity of the inner wall of a discharge tube corresponding to an inlet to equalize the gas flow rate in the tube. CONSTITUTION:When gas medium 6 in a cooling passage 9 is flown from an inlet 10 into a discharge tube 2, it is branched into upper and lower sides 1A and 1B of the inner wall surface of the tube 2 corresponding to the inlet 10. Since the gas medium 6 flown into the upper side 1A is throttled at a projection 13 to become difficult to be flown to a rectifier 14, the gas stream becomes decelerated. Since the gas medium 6 flown into the lower side 1B, on the other hand, collides with the projection 13 and guided by the projection 13 to pass through the rectifier 12, the gas stream is accelerated. Thus, the gas stream is substantially equalized to cool the cathode 5 uniformly.
