Abstract
The present invention employs a laser apparatus including: a cavity provided with reflecting means and output means; a gain member placed on an optical path between the reflecting means and the output means; a wavelength dispersion mechanism that disperses a light beam passing through the optical path; and a wavelength selecting mechanism including a wedge prism which is movable relative to the optical path and changes a traveling direction of a light beam, the wavelength selecting mechanism being configured to change a wavelength of a light beam to be outputted from the output means by being given a gain by the gain member in accordance with a position of the wedge prism, the wavelength dispersion mechanism including a prism which is positioned on the optical path to allow a light beam traveling on the optical path to become incident on the prism at Brewster's angle.
