We report time-resolved measurements of transient optical absorption and emission in nominally pure CaF2 crystal. For excitation we used a pulse of accelerated electrons. It was shown that irradiation leads to the formation of centers of induced abso

Optical spectroscopy with nanosecond resolution has been used to study how the prehistory (the presence of impurities, heat treatment) of CaF2 crystals affects the processes of creating autolocalized excitons (AEs) under the influence of a pulse of a

The method of absorption spectroscopy with nanosecond resolution is used to study transient absorption in nominally pure crystals of CaF2 irradiated by a pulse of fast electrons. Optical absorption caused by self-trapped excitons appears in the form
