Abstract

In a Y₂SiO₅:Pr³⁺ crystal characterized by two non-equivalent Pr³⁺ optical centers, the interaction mechanisms between Pr³⁺ ions as well as between Pr³⁺ ions and a crystal lattice have been studied. It has been shown that along with the electron-phonon interaction, the interaction between Pr³⁺ ions and two-level systems made an additional contribution to the homogeneous linewidth of the ³H₄↔³P₀ optical transition. Two different mechanisms of the Pr³⁺ interionic coupling have been found. The first mechanism is associated with a dipole-dipole interaction between non-equivalent Pr³⁺ optical centers, while the other one is governed by a cooperative cross relaxation of the excitation energy among the same type Pr³⁺ optical centers.
