Abstract

This paper reports the high-temperature top-seeded solution growth (TSSG) of large single crystal of Nd³⁺-doped GdAl₃(BO₃)₄ from a K₂Mo₃O₁₀-LiF flux cooled at a rate of 2 K/day and using a crystal rotation rate of 4.5 rpm. Thepolarized optical absorption and fluorescence spectra of Nd³⁺ : GdAl₃(BO₃)₄ crystal have been investigated. Polarized absorption cross sections are 4.3x10^-20 and 2.6x10^-20 cm² with band widths of 8.7 and 6.1 nm for σ- and π-polarization, respectively. The emission cross sections are 6.3x10^-19 and 6.0x10^-19 cm² for σ- and π-polarization, respectively, at 1062 nm corresponding to the ⁴F_3/2→⁴I_11/2 transition. The fluorescence lifetime is 54.3 and 57 μs at 300 and 20 K, respectively.
