PURPOSE: To contract the size of a gas laser generator by inclining and disposing to approach outlets of blowers which are provided at mixture gas suction inlets of two discharge tube bodies, thereby reducing the size of the width of the blowers.
CONSTITUTION: Suction outlets 13 for mixture gas 4 are formed at both ends of the first discharge tube body 2 and the second discharge tube body 3, and suction inlets 14 are formed at the intermediate of both discharge tube bodies between suction outlets 13. Since the outlets 22, 23 of the first centrifugal blower 20 and the second centrifugal blower 21 form oblique surfaces 24 so as to approach each other, flanges 15A are not projected outside. The size of the width of the centrifugal blowers becomes L2, thereby reducing the size of a gas laser generator 1.
