Abstract

PURPOSE:To select the wavelength of a laser device by inclining a reflecting mirror having a curvature with a simple structure by providing a thick laser tube of laser window between a reflecting mirror having large curvature and a planar mirror. CONSTITUTION:A laser tube 11 having a thick window 12 and a reflecting mirror 13 made of a pair of reflecting mirrors and having large radius of curvature are disposed at the window 12 side. The optical path of oscillation is at the window 12, and is isolated at every wavelengths 15, 16. A spherical reflecting mirror 13 is perpendicular to the optical path 15, and oscillates in the wavelength of the optical path 15, and since the optical path 16 does not cross perpendicularly the spherical reflecting mirror 13, it does not oscillate. When the reflecting mirror 13 is inclined to perpendicularly cross the optical path 6, the optical path 16 will oscillte. In this manner the wavelength can be selected with simple structure.
