Regimes for High-Temperature Annealing for KO-1 and KO-5 Ceramics by CO2 Laser Radiation

Abstract

Nondestructive regimes of high-temperature laser annealing of KO-1 and -5 optical ceramic by CO 2 laser radiation are determined within the framework of the quasistatic uncoupled problem of thermoelasticity for an isotropic plate. The processing regime with short-time action results in a large increase of the required laser radiation power density and a decrease of the require energy density. The processing regime with long-time action results in a decrease of the required energy density. The adequacy of the computational model is checked experimentally.
