Abstract

This paper reports the high-temperature top-seeded solution growth (TSSG) of large single crystal of Nd3+-doped GdAl3(BO3)4 froma K2Mo3O10-LiF flux cooled at a rate of 2 K/day and using a crystal rotation rate of 4.5 rpm. The polarized optical absorption and fluorescence spectra of Nd3+ : GdAl3(BO3)4 crystal have been investigated. Polarized absorption cross sections are 4.31020 and 2.61020 cm2 with band widths of 8.7 and 6.1 nmfor s- and p-polarization, respectively. The emission cross sections are 6.31019 and 6.01019 cm2 for s- and p-polarization, respectively, at 1062 nmcorresponding to the 4F3/2-4I11/2 transition. The fluorescence lifetime is 54.3 and 57 ms at 300 and 20 K, respectively.
