1. A solid-state laser apparatus comprising:

  • a master oscillator configured to output laser light having at least one longitudinal mode, the master oscillator being capable of changing the spectral linewidth of the laser light output therefrom;

    at least one amplifier located downstream of the master oscillator on an optical path;

    a wavelength converter located downstream of the amplifier on the optical path;

    a detector configured to detect a spectrum of the laser light; and

    a controller configured to control the spectral linewidth of the laser light output from the master oscillator based on a detection result of the detector.
