Abstract
The present invention relates to a solid-state laser module, and so on, having a structure for enabling optical output of high quality to be obtained. The solid-state laser module includes a vacuum container with windows, and a heat sink, a solid-state laser medium, and a pair of transparent members are housed in the vacuum container in an integrally assembled state. The solid-state laser medium and the pair of transparent members respectively have disk shapes, and the pair of transparent members sandwich the solid-state laser medium. The thermal conductivity of each of the pair of transparent members is higher than the thermal conductivity of the solid-state laser medium. The heat sink has a shape that simultaneously clamps portions of the pair of transparent members that sandwich the solid-state laser medium in between, and a heat insulating region, with a thermal conductivity that is lower than the thermal conductivity of the solid-state laser medium, is provided between the heat sink and the solid-state laser medium.
