Title: Laser oscillator
Inventor: KARUBE NORIO
IPC: H01S3/20
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To suppress a resonator loss caused by grain boundary diffusion, while securing a large gain volume by using a granular laser gain medium. SOLUTION: A suspension 1 with dielectric grains, which are doped with light-emitting elements such as lanthanoid, diffused in a solvent composed of an index-matching fluid in a suspended state is sealed into a cell 6 and arranged inside an optical resonator composed of a rear mirror 3 and an output mirror 4. The cell 6 is slab-shaped, and its end face is worked into the Brewster's angle. When the cell 6 is irradiated with excitation light 2, the dielectric grains in the suspension 1 are excited by lasers, and laser light 5 is outputted. Since the dielectric grains coexist in the index-matching fluid, the grain boundary diffusion is suppressed and a low-loss optical resonator can be provided. It is also available to slightly enlarge the diameter of dielectric grains and to diffuse them in the index-matching fluid filling liquid.  The circulation system of the suspension 1 or filling liquid is connected to the cell 6 and discharging/ cooling can be performed as well.

When water is fed in the container 1, the floating heat insulating material 31 floats on the water surface because the specific gravity of the floating heat insulating material is 1 or lower. Then, when the water is boiled by a heater 2, a vapor rises from the gap between the floating heat insulating material 31 and the inner periphery of the container 1, and is diffused from a vapor port 8 through a vapor passage 10. During a heat insulation, the floating heat insulating material 31 floats on the water surface, comes directly into contact with the hot water, and reduces a heat radiation from the upper portion of the container 1. Also, since the floating heat insulating material 31 is always in contact with the water surface and moves in the vertical direction following the change of the water surface after a hot water feeding, and a space is not formed above the water surface, and the water surface is heat-insulated by the floating heat insulating material 31.
