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 …
