Abstract
The laser-induced vacuum-ultraviolet fluorescence spectra of KY3F10:Nd 3+ (KYF:Nd) and YF3:Nd3+ (YF:Nd) single crystals pumped by a pulsed-di scharge molecular F-2 laser at 157 nm were obtained. A number of new f luorescence peaks were observed and were assigned to the 4f(2)5d --> 4 f(3) dipole-allowed transitions of the Nd3+ ion. The absorption spectr a of LiYF4:Nd3+ (YLF:Nd), KYF:Nd, and YF:Nd crystal samples in the vac uum-ultraviolet spectral regions were also obtained. Finally, the spli tting of the states of the 4f(2)5d configuration of the Nd3+ ion, whic h is due to the crystal field, was observed in all the crystal samples .
