The spectral and kinetic parameters of
electron-pulse-initiated transient absorption and luminescence of nominally
pure CaF2 crystals were studied using pulsed spectrometry with
nanosecond time resolution. The effect of
temperature on the formation of defects was studied. It was established that on
increasing the temperature F-H pairs and unknown defects are created.
Laser-induced change is studied by optical absorption and luminescence due to
F-H pairs generated by an electron pulse in CaF2.
