Abstract
One optical base is provided on each side of a housing that houses a laser oscillator. Optical parts of an optical resonator are fixed to the optical bases. The optical bases are fixed to each other, independently from the housing, by supporting rods. A plate spring and two dampers fix the respective optical base to respective end of the housing. The plate spring bends in the direction of the laser beam when the housing deforms. The damper attenuates oscillation generated due to the displacement of the housing.
