Thermal-and-Optical Characteristics of Refractory Dielectric in Intensive Radiation Field. Part 1. Experimental Diagnostic Optical and Heat-Physical Module of "Luch"

The optical and heat-physical diagnostic module of the "Luch" stand developed for the study of optical characteristics of construction materials - emission and absorption ones, IR-VUV spectra within wide ranges of quantum energy (0.1...100 eV) and temperatures (300 K < T < T_melting) is described. Experimental and analytical results are presented of the study of optical and heat-physical characteristics of high temperature dielectric materials (Al₂O₃, BNC, SiO₂) in the field of the intensive coherent radiation at standard laser frequencies and under the wide band heat radiation in the UV-VUV spectrum range.
