Abstract
A laser device includes a laser medium for amplifying seed light, a first optical system for outputting excitation light for exciting the laser medium and causing the excitation light to be incident on the laser medium and input to an excitation region of the laser medium, and a second optical system for causing the seed light of first polarization to be incident on the laser medium at an incidence angle larger than 0° with respect to the laser medium and input to the excitation region.
