<p>The present invention uses a laser apparatus capable of selecting a wavelength of light to be outputted from a plurality of wavelengths, including: a branching unit which is formed of a polarizer (804) and is configured to branch an optical path formed in a resonator including a reflecting unit having a plurality of fixed reflecting planes and an output mirror (802), into a plurality of optical paths, thereby forming a common optical path (809) having an end defined by the output mirror (802) and a plurality of optical path branches (810,811) each having an end defined by any one of the reflecting planes (807,808); a laser medium (803) disposed in the common optical path (809); and a selecting unit (805) configured to select, from the plurality of optical path branches (810,811), an optical path branch which corresponds to a wavelength of light to be outputted. The selecting unit (805) may be a Pockels cell which can take in addition the function of a Q-switch.</p> |
