Abstract:
1. 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 such that a contact surface of said first member is 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 such that a contact surface of said second member is 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 solid-state heat insulating member, 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, said solid-state heat insulating member having a first main surface being in direct contact with said contact surface of said first member and a second main surface being in direct contact with said contact surface of said second member, wherein the contact surface dimension of said first member is approximately equal to the overall first main surface dimensions of said solid-state laser medium and said solid-state heat insulating member, and the contact surface dimension of said second member is approximately equal to the overall second main surface dimensions of said solid-state laser medium and said solid-state heat insulating member.
