Optical Spectroscopy of Barium Fluoride Crystals under Simultaneous Pulsed Excitation

Abstract:

This paper reports optical absorption spectra and rapidly decaying luminescence of BaF₂ crystals measured at 295 K under excitation pulse of accelerated electrons and excited simultaneous stimulated emission of CdSe crystal. It is shown that the simultaneous excitation of the crystals BaF₂ pulse accelerated and SE semiconductors in electronic components STE absorption leads to a reduction efficiency of creation of STE and the appearance of fast decaying emission in the UV region of the spectrum.
