On the interconfigurational 4f25d-4f3 VUV and UV fluorescence features of Nd3+ in LiYF4 (YLF) single crystals under F2 laser pumping

Abstract

Fluorescence spectra and kinetics of LiYF4(YLF):Nd3+ single crystals pumped by an F2 pulsed discharge molecular laser at 157 nm have been obtained in the VUV and UV regions of the spectrum between 150-300 nm. With this pumping scheme some new fluorescence peaks have been observed. The high photochemical stability of this material under the above pumping scheme suggests that it can be used as an active medium for VUV tunable laser sources. ft]1|Permanent address: Kazan State University, 18 Lenin Str., 420008 Kazan, Russian Federation. © 1992.
