✦ Synopsis

Nd:LuVO 4 single crystal has been grown by Czochralski method. Optical absorption bands of Nd:LuVO 4 crystal have been measured and assigned to transitions between the energy levels of Nd 3+ . From the optical absorption measurements, intensity parameters (X t (t = 2, 4, 6)) have been calculated and the results were X 2 = 7.182 β€’ 10 Γ€20 , X 4 = 5.990 β€’ 10 Γ€20 and X 6 = 5.779 β€’ 10 Γ€20 cm 2 by using Judd-Ofelt theory, respectively. Radiative lifetimes (s rad. ), branching ratios of the fluorescence emission (b J 00 J 0 ) and the integrated emission cross-section P Γ°J 00 ! J 0 Þ have also been theoretically estimated and reported for certain fluorescent levels. The thermal, optical and laser properties of Nd:LuVO 4 crystal are compared with those of Nd:YVO 4 and Nd:GdVO 4 crystals, and the results show that Nd:LuVO 4 crystal is a potential laser crystal.
