dc.description.abstract The Laser Induced Fluorescence (LIF) spectrum of K2YF5:Nd3+ (PFYK:Nd) and LiYF4:Nd3+ (YLF:Nd) single crystals, pumped by the fluorine F2 pulsed discharge molecular laser at 157.6 nm, was obtained in the Vacuum Ultraviolet (VUV) region of the spectrum. The fluorescence peaks were assigned to the 4f25d → 4f3 dipole allowed transitions of the Nd3+ ion. The 180 nm band of the LIF spectrum from the crystals indicates that the 4f25d → 4f3 dipole transitions originate from the low Stark components of the 4K11/2 level of the 4f25d configuration. The absorption spectrum of the crystal samples in the VUV was obtained as well and spectroscopic assignment of the levels of the 4f25d configuration was made. The electric crystal field splits all the levels of single and mixed configuration. The energy of the Stark components of the 4f25d configuration in YLF:Nd was shifted by few hundred cm-1 relative to that of PFYK:Nd. We observed eleven and nine dipole transitions, between the 4I9/2 ground level of the 4f3 configuration and the Stark components of the levels of the 4f25d configuration of the Nd3+ ion, in YLF and PFYK crystal hosts, respectively. © 1998 Elsevier Science B.V.
