Claim Text:
1. A laser apparatus comprising: a laser medium; a light source that radiates light to said laser medium, and excites said laser medium; a reflecting unit having a first portion that reflects light within a first wavelength range from light generated by excitation of said laser medium and a second portion that reflects light within a second wavelength range from light generated by excitation of said laser medium; and an output mirror arranged opposite said reflecting unit, with said laser medium being arranged therebetween, causing laser oscillation by inducing resonance of the light within said first wavelength range between said first portion and said output mirror and causing laser oscillation by inducing resonance of the light within said second wavelength range between said second portion and said output mirror, wherein said reflecting unit and said output mirror constitute a resonator, wherein said reflecting unit moves in a linear direction so as to switch a first position in which the laser apparatus is set in an oscillation state of the light within said first wavelength range by using said first portion, a second position in which the laser apparatus is set in an oscillation state of the light within said second wavelength range by using said second portion, and a third position in which the laser apparatus is set in a non-oscillation state, said linear direction being a direction intersecting with an arrangement direction of said first portion, said laser medium and said output mirror in a state in which said reflecting unit is in the first position.
