POLYCRYSTALLINE LASER MATERIAL

摘要

FIELD: physics. ^ SUBSTANCE: polycrystalline laser material is a microstructured substance with grain size from 3 mcm and consists of calcium and ytterbium fluorides. The material is a solid solution of calcium fluoride and ytterbium fluoride. Content of ytterbium fluoride is less than 5 mol %. The base of the structure of the material is composed of layered grains in which layer thickness ranges from 30 to 100 nm, and the size of separate grains ranges from 30 to 150 mcm. ^ EFFECT: improved optical characteristics and thermal conductivity of the laser material. ^ 2 dwg
