ABSTRACT:
A gas laser apparatus for generating a laser beam along a light beam axis, comprises, a gas as a laser medium, a dielectric tube through which the gas passes, and which surrounds the light beam axis, a pumping source generating an electric discharge through the gas existing in the dielectric tube to excite the gas so that a laser light is generated from the excited gas, and a gas blower blowing the gas into the dielectric tube, wherein the gas blower forms a circumferential flow direction component of the gas in the dielectric tube.
