LASER APPARATUS AND CONTROL METHOD THEREFOR

摘要

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 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, into a plurality of optical paths, thereby forming a common optical path having an end defined by the output mirror and a plurality of optical path branches each having an end defined by any one of the reflecting planes; a laser medium disposed in the common optical path; and a selecting unit configured to select, from the plurality of optical path branches, an optical path branch which corresponds to a wavelength of light to be outputted.

1. A laser apparatus capable of selecting a wavelength of light to be outputted from a plurality of wavelengths, comprising:
a branching unit which is formed of a polarizer 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, into a plurality of optical paths, thereby forming a common optical path common to the plurality of optical paths which has an end defined by said output mirror and a plurality of different optical path branches respectively corresponding to the plurality of optical paths and each having an end defined by any one of said reflecting planes of said reflecting unit; a laser medium disposed in the common optical path; and a selecting unit configured to select, from the plurality of optical path branches, an optical path branch which corresponds to a wavelength of light to be outputted.
