Title: Narrow band laser device
Inventor: FURUYA NOBUAKI
IPC: H01S3/08
Filed: 1990-01-12
Abstract: PURPOSE:To prevent a narrow band laser device from fluctuating in wavelength and deteriorating in output due to the deformation and the deterioration of a wavelength selection element by a method wherein a grating is provided in a resonator optical path other than an output optical path which extends from a laser medium through a polarization separating prism. CONSTITUTION:A discharge tube 1 starts oscillating through discharge excitation, light amplified through the laser medium is made to pass through a polarization light separating prism 5 and outputted as an output light 12, and a grating 6 serving as a wavelength selection element is provided in a resonator optical path other than the output optical path between a polarized light separating prism 5 and a first total reflection mirror 2 to enable only light of narrow band specified in wavelength to pass through it. Light specified in plane of polarization is converted in plane of polarization through a wavelength phase shifter 4, amplified through the laser medium, and outputted as an output light through the polarized light separating prism 5. By this setup, optical energy passing through the wavelength selecting element 6 is made to decrease to such an extent that the output light is divided by the amplification factor of the laser medium, and a wavelength selection element is sharply decreased in deformation and deterioration.

Abstract: PURPOSE:To decrease the storing amount of uranium to a large extent by reducing spent oxide fuel in specified molten salt, transforming the fuel into the metal form, dissolving the metal in a Fe-U bath, performing electrolysis, and depositing and recovering uranium. CONSTITUTION:In an electrolytic refining tank 17, an Fe-U bath 5 containing depleted uranium and a KCl-LiCl bath 18 on the bath 5 are provided. An iron cathode 13 is provided in the bath 18. A testing device is provided in a globe box 22 having argon atmosphere. The bath 5 is used as the anode, and the iron core 13 is used as the cathode. Then, electrolytic refining is performed at a temperature, at which the Fe-U become the fused state. The depleted uranium which is present in the bath 5 undergoes anodic oxidation and becomes trivalent ion UCl3, which is moved into the bath 18. The ion UCl3 is reduced with the cathode 13 and deposited on the surface. In the electrolytic refining, the metal uranium, which is deposited in a Ca reducing step and an extracting step at the previous state, is dissolved in the bath 5 accompanying the decrease in concentration of the uranium in the bath. Therefore, the metal uranium can be continuously recovered. Thus, the temporary storing amount of the depleted uranium can be decreased to a large extent.
