Abstract:
1. A planar waveguide laser device that forms a waveguide by a plate-like laser medium having birefringence and clad attached to at least one of surfaces of the laser medium perpendicular to a thickness direction thereof, amplifies laser light by a gain produced by excitation light incident on the laser medium, and performs laser oscillation, wherein the laser medium is formed of a birefringent material that has an optic axis on a cross section perpendicular to a light axis that is a direction in which the laser light travels, and the clad is formed of an optically isotropic material having a refractive index in a range between refractive indexes of two polarized lights that travel along the light axis in the laser medium and have oscillation surfaces that are orthogonal to each other.
