Nd:Y3ScxAl5-xO12 (x= 0.05, 0.5, 1) shaped crystals grown by the micro-pulling-down method and optical properties

Abstract

Nd3+ doped Y3ScxAl5-xO12 (x = 0.05, 0.5, 1) single crystals were successfully grown by the micro-pulling-down (μ-PD) technique. The effect of compositional parameter x on the structure, absorption, emission and fluorescence lifetime of Nd:Y3ScxAl5-xO12 crystals was studied. The Nd3+ concentration in the core increased with increasing of compositional parameter x. The full width at half maximum (FWHM) of the emission band centered at 1064 nm was calculated to be 6.1, 7.1, and 7.3 nm for x = 0.05, 0.5 and 1, respectively. The fluorescence lifetimes of 4F3/2 levels are 259.3, 269.6, and 276.9 μs for x = 0.05, 0.5, and 1, respectively. The results indicate that the Nd:Y3ScxAl5-xO12 crystals are promising materials for laser output.
