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 ⁴K_11/2 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 ⁴I_9/2 ground level of 4f³ configuration and the Stark components of the levels of 4f²5d configuration of the Nd³⁺ ion.
