VUV and UV fluorescence and absorption studies of Nd3+ and Ho3+ ions in LiYF4 single crystals

The laser induced fluorescence spectra of LiYF4:ND3+ (YLF:Nd) and LiYF4:Ho3+ (YLF:Ho) single crystals, pumped by an F2 pulsed discharge molecular laser at 157 nm were obtained in the vacuum ultraviolet (VUV) and ultraviolet (UV) regions of the spectrum. With this pumping arrangement a number of new fluorescence peaks were observed for the first time. They are assigned to the dipole allowed transitions 4f25d→4f3 and 4f95d→4f10 of the Nd3+ and Ho3+ ions, respectively. The absorption spectra of the same crystal samples in the VUV and UV spectral regions were taken as well. © 1994

Vacuum-ultraviolet interconfigurational 4f3 → 4f 25d absorption and emission studies of the Nd3+ ion in KYF, YF, and YLF crystal hosts

The laser-induced vacuum-ultraviolet fluorescence spectra of KY 3F10:Nd3+ (KYF:Nd) and YF3:Nd 3+ (YF:Nd) single crystals pumped by a pulsed-discharge molecular F2 laser at 157 nm were obtained. A number of new fluorescence peaks were observed and were assigned to the 4f 25d → 4f3 dipole-allowed transitions of the Nd3+ ion. The absorption spectra of LiYF4:Nd3+ (YLF:Nd), KYF:Nd, and YF:Nd crystal samples in the vacuumultraviolet spectral regions were also obtained. Finally, the splitting of the states of the 4f25d configuration of the Nd 3+ ion, which is due to the crystal field, was observed in all the crystal samples. © 1995 Optical Society of America

VUV and UV fluorescence and absorption studies of tb3+ and tm3+ trivalent ions in liyf4 single crystal hosts

The laser induced fluorescence spectra of LiYF4: Tb3+ (YLF: Tb) and LiYF4:Tm3+ (YLF: Tm) single crystals, pumped by an F2 pulsed discharge molecular laser at 157 nm, were obtained in the vacuum ultraviolet (VUV) and ultraviolet (UV) regions of the spectrum, at room temperature. A number of new fluorescence peaks were observed for the first time. They were assigned to the dipole allowed transitions 4f75d→4f8 and 4f115d→4f12 of Tb3+ and Tm3+ ions respectively. The absorption spectra of the same crystal samples in the VUV and UV regions were taken as well. The edge (onset) and the energy of the states with 4fN-1 5d configuration were determined. © 1994 Taylor and Francis Ltd
