摘要： A process for producing a polarizing glass containing shape-anisotropic metallic particles dispersed in an oriented state therein, which comprises drawing a glass preform containing metallic halide particles dispersed therein while its viscosity being held above 2×106, but below 7×107 poises; and subjecting the drawn glass to a reducing treatment so that a part or all of the metallic halide particles are reduced to metallic particles, which process enables it to produce a polarizing glass with a high yield from a starting material of a glass containing metallic halide particles, while avoiding glass breakage or fracture during elongation as well as preventing the elongated metallic halide particles from returning to a spherical shape.

摘要： A composite slab laser medium provided with a non-doped layer containing substantially no laser active materials and a first and second doped layers provided at both sides of the non-doped layer, respectively, in such a manner to hold the non-doped layer, each of which contains a laser active material. In this composite slab laser, a first surface of the first doped layer and a second surface of the second doped layer are in contact with the outside of the composite slab laser medium and are parallel with each other. Further, a laser oscillation or an optical amplification is performed by extracting a laser beam which travels in a zig-zag path undergoing total internal reflection at the first and second surfaces employed as alternate reflecting surfaces within the composite slab laser medium. Moreover, layers made of laser glass containing Nd.sub.2 O.sub.3 of from 3 to 9% by weight is employed as the doped layers. Furthermore, a total of the thicknesses of the first and second doped layers is of from 0.6 to 8.0 mm. Additionally, the ratio of the total of the thicknesses of the first and second doped layers to the thickness of the whole composite slab laser medium is of from 0.075 to 0.40. Thereby, a composite slab laser medium, the gain of which is well balanced with the cross section of a laser beam, can be realized. Further, a laser provided with such a laser medium and a pump source for optical pumping of the laser medium can be provided. Thereby, a laser capable of emitting a laser beam with a high-beam-quality and high-peak-power can be realized.
