Kinetics of subthreshold luminescence and microwave conductivity of glasses under laser heating conditions

An experimental investigation was made of the luminescence and microwave conductivity of K8 and ZhS 11 optical glasses under conditions of subthreshold irradiation by a quasi-cw neodymium laser. For ZhS 11 glass it was established that the luminescence depended on temperature and the influence of photostimulation was observed at the 1.06 μ wavelength. The activation energies of the microwave conduction and subthreshold luminescence processes were determined for ZhS 11 glass.
