Abstract:
1. A laser apparatus capable of emitting laser beams of a plurality of different wavelengths, the apparatus including: an exciting light source; a solid-state laser medium which emits light of a plurality of peak wavelengths by light from the exciting light source; a rotatable reflection mirror placed so that a line that is perpendicular to a reflection surface of the rotatable reflection mirror is inclined at a predetermined non-zero angle with respect to a resonance optical axis of the laser medium; a rotating unit, having a rotating axis made coaxial with or parallel to the resonance optical axis, which rotates the rotatable reflection mirror about the rotating axis so that the rotatable reflection mirror is disposed changeably between a first position and a second position and the predetermined inclined non-zero angle of the line that is perpendicular to the reflection surface with respect to the resonance optical axis is constant; a first resonance optical system including: a second resonance optical system including:
