摘要： In a laser device, a control range of focal distance of a generated thermal lens is broadened and reliability is improved. A mode control waveguide-type laser device includes: a planar laser medium having a waveguide structure in a thickness direction of a cross section perpendicular to an optical axis, for generating gain with respect to laser light; a cladding bonded onto the laser medium; and a heat sink bonded onto the laser medium. The laser medium generates a lens effect, and the laser light oscillates in a waveguide mode in the thickness direction, and oscillates in a spatial mode due to the lens effect in a direction perpendicular to the optical axis and the thickness direction. The refractive index distribution within the laser medium is created by generating a temperature distribution in the laser medium depending on a junction area of the cladding and the heat sink.

摘要： A planar waveguide laser device forms a waveguide by a plate-like laser medium having birefringence and clad attached to at least one of the surfaces of the laser medium perpendicular to its thickness direction, amplifies laser light by a gain produced by excitation light incident on the laser medium, and performs laser oscillation. The laser medium is formed of a material having an optic axis on a cross section perpendicular to the light axis, which is the laser travelling direction. The clad is formed of a 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. The planar waveguide laser device readily oscillates linearly polarized laser light.
