“…Nd 3+ -doped yttrium scandium aluminum (Nd:Y 3 Sc x Al 5-x O 12 ) compositions are considered as solid solution of Nd:YAG and Nd:Y 3 Sc 2 Al 3 O 12 (Nd:YSAG) [3]. These crystals have some advantages in comparison to Nd:YAG crystal [4][5][6][7][8]. In the lattice, Sc 3+ and Al 3+ ions are randomly distributed on the octahedral positions.…”

“…Nd:Y 3 Sc x Al 5-x O 12 crystals has been grown by the Czochralski method [6], floating zone method [7] and micro-pulling-down method [8]. The μ-PD method has the capability to produce under stationary stable regime single crystalline materials quickly, relatively inexpensively and the grown samples are of sufficient dimensions for the microscopic and macroscopic characterization [9][10][11][12].…”

Nd 3+ doped Y 3 Sc x Al 5-x O 12 (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:Y 3 Sc x Al 5-x O 12 crystals was studied. The Nd 3+ 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 lifetime of 4 F 3/2 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:Y 3 Sc x Al 5-x O 12 crystals are promising materials for laser output.
