Paper Abstract

The laser induced fluorescence (LIF) spectrum of LiCaAlF:Nd3+ (LiCAF:Nd) single crystal, pumped by an 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 4f25dyields4f3 dipole allowed transitions of the Nd3+ ion. The LIF spectrum of the crystals, indicates that the 4f3yields4f25d dipole transitions, originate from the low Stark components of the 4K11/2 level of 4f25d configuration. The absorption spectrum of the crystal samples in the VUV was obtained as well. The electric crystal field splits all the levels of 4f25d mixed configuration. We observed seven dipole transitions, between the 4I9/2 ground level of 4f3 configuration and the Stark components of the levels of 4f25d configuration of the Nd3+ ion.
