ABSTRACT:
There is prevented mirrors from being misaligned owing to a thermal expansion difference caused by temperature distribution along constituent portions of an argon ion laser supporting the mirrors to improve the stability of a laser output. For this purpose, a member having a thermal expansion coefficient to cancell a thermal expansion difference is joined with any of portions of the cathode bulb supporting the mirrors both constituting an optical resonator, said portions demonstrating a temperature difference.
