Parametric spectroscopy of the kinetics of luminescence from color centers in KCl and KBr crystals

An investigation was made of the kinetics of infrared luminescence from color centers in KCl and KBr crystals using temporal parametric spectroscopy. It was shown that the infrared luminescence spectrum of color centers excited by YAG laser radiation consists of two bands with significantly different lifetimes. Parametric spectroscopy was used to resolve and identify these bands as transitions of the R_F →R_N and R_N →0 types. Investigations were made of optimal Q switching of a laser resonator using a KCl crystal.
