Spectroscopic properties of LHPG-grown Nd:LuxY3-xAl5O12 single crystal fibers

Abstract

Nd:LuxY3-xAl5O12 (x = 0, 1, 1.5, 2, 3) crystal fibers doped with 0.2 at.% Nd3+ were successfully grown using the laser-heated pedestal growth (LHPG) method. The effects of the Lu3+/Y3+ ratio on the structural, absorption, and emission properties were systematically studied. Absorption spectra show that Nd:LuxY3-xAl5O12 (Nd:LuYAG) crystal fibers combine the high absorption cross section of Nd:YAG and the broad absorption bandwidth of Nd:LuAG. Judd-Ofelt analysis was employed to evaluate the optical transition parameters. Under 808 nm excitation, the fluorescence lifetime of the F-4(3/2) level gradually decreased with increasing Lu3+ content. These results indicate that adjusting the Lu3+/Y3+ ratio in Nd:LuYAG crystal fibers allows optimization for high-performance laser applications, presenting a potential alternative to conventional Nd:YAG gain media.
