Abstract

The inter-Stark components of the ⁴I_9/2 and ⁴I_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 Nd³⁺ in LLGG laser crystal at 80 K. The thermal effects on the linewidths, positions, and line shifts of the 933.6 (R₁→X₅) and 1057.3 (R₂→Y₃) nm lines within the respective intermanifold transitions of ⁴F_3/2→⁴I_9/2 and ⁴F_3/2→⁴I_11/2 have also been investigated. The linewidths of these transitions are found to increase with increasing temperature. The 933.6 nm line is found to shift towards the shorter wavelength, while the 1057.3 nm has shifted towards the longer wavelength. The experimental results of the temperature-dependent widths and shifts of these sharp spectral lines are explained using the phonon-ion interaction theory, which assumes the Debye model for phonons in crystalline solids.
