Abstract
A laser system includes a light amplifier medium provided with an optical waveguide layer which controls the transverse mode to a fundamental transverse mode in one direction, a first resonator mirror optical system which is opposed to a first light outlet end face of the light amplifier medium and reflects a laser beam radiated from the first light outlet end face to impinge upon the first light outlet end face, and a second resonator mirror optical system which is opposed to a second light outlet end face of the light amplifier medium and reflects a laser beam radiated from the second light outlet end face to impinge upon the second light outlet end face. At least one of the first and second resonator mirror optical system includes a collimator optical system which collimates the amplitude distribution in the laser beam radiated from the corresponding light output end face of the light amplifier medium at least in a direction substantially perpendicular to the optical waveguide layer, and a reflecting optical system which converts amplitude distribution in the direction substantially perpendicular to the optical waveguide layer in the collimated laser beam to amplitude distribution in a direction substantially parallel to the optical waveguide layer and reflects the laser beam.
