摘要

The inter-Stark components of the ~4I_9/2 and ~4_11/2 manifolds have been characterized using the fluorescence spectra for the ~4F_3/2→~4I_9/2 and ~4F_3/2→~4I_11/2 transitions of Nd~3+ in LLGG laser crystal at 80 K. The thermal effects on the linewidths, positions, and line shifts of the 933.6 (R_1→X_5) and 1057.3 (R_2→Y_3) nm lines within the respective in- termanifold transitions of ~4F_3/2→~4I_9/2 and ~4F_3/2→~4_11/2 have also been investigated. The linewidths of these tran- sitions are found to increase with increasing temperature.
