摘要	A solid laser module etc. having a structure that enables to obtain a high-quality light output. The solid laser module has a vacuum container with a window, and a heat sink, a solid laser medium, and a pair of transparent members are received in an integrally assembled state in the container. The solid laser medium and the pair of transparent members are each formed in a disc shape, and the solid laser medium is sandwiched between the pair of transparent members. The thermal conductivity of each of the pair of transparent members is higher than the thermal conductivity of the solid laser medium. The heat sink is shaped to simultaneously hold portions of the pair of transparent members that hold the solid laser medium in between. A heat insulation region having a lower thermal conductivity than the solid laser medium is provided between the heat sink and the solid laser medium.
其他摘要	一种固体激光模块等，具有能够获得高质量光输出的结构。固体激光模块具有带窗的真空容器，散热器，固体激光介质和一对透明构件以整体组装的状态容纳在容器中。固体激光介质和一对透明构件均形成为盘状，并且固体激光介质夹在一对透明构件之间。该对透明构件中的每一个的导热率高于固体激光介质的导热率。散热器成形为同时保持一对透明构件的部分，该部分透明构件将固体激光介质保持在其间。在散热器和固体激光介质之间提供具有比固体激光介质低的导热率的隔热区域。
主权项	A solid-state laser module comprising: a solid-state laser medium, doped with an active element that is pumped by the pumping light with a first wavelength, generating emission light with a second wavelength into its interior in response to illumination of the pumping light; a first member provided in a state of being in direct contact with a first main surface of said solid-state laser medium, said first member being comprised of a material transparent to both the pumping light and the emission light, and having a higher thermal conductivity than said solid-state laser medium; a second member provided in a state of being in direct contact with a second main surface said solid-state laser medium that opposes the first main surface, said second member being comprised of a material transparent to both the pumping light and the emission light, and having a higher thermal conductivity than said solid-state laser medium; a heat sink provided so as to clamp at least a portion of each of said first and second members that sandwich said solid-state laser medium therebetween, in a state of being separated by a predetermined distance from said solid-state laser medium; and a heat insulating region, provided between said heat sink and side surfaces of said solid-state laser medium that communicates between said first and the second main surfaces, having a lower thermal conductivity than said solid-state laser medium.
