Parameters for high-temperature laser annealing of KO-1 and KO-5 optical ceramics with СО2-radiation

Within the framework of a quasi-static uncoupled problem of thermoelasticity for an isotropic plate, non-destructive modes of high-temperature laser annealing of optical ceramics KO-1 and KO-5 with CO ₂ laser radiation are determined. The treatment mode with a short exposure time leads to a significant increase in the required power density of laser radiation and a decrease in the required energy density. The treatment mode with a long exposure time leads to a decrease in the required power density of laser radiation, but causes a significant increase in the required energy density. An experimental verification of the adequacy of the computational model has been carried out.
