Spectroscopic properties and energy transfer parameters of Tm3+ ions in GaLaS chalcogenide glass

Spectroscopic properties and energy transfer parameters of Tm3+ ions in GaLaS chalcogenide glass
Spectroscopic properties and energy transfer parameters of Tm3+ ions in GaLaS chalcogenide glass
This work presents the spectroscopic characterization of Tm3+doped GaLaS chalcogenide glass and a study on Tm3+:Tm3+ energy transfer. The cross relaxation 3H4,3H6 to 3F4,3F4, responsible for the laser emission at 1.8 µm, and the energy migration 3H4,3H6 to 3H4,3H6 processes are studied in terms of the microscopic parameters of energy transfer Cda and Cdd obtained by the Kushida model of multipolar interaction and by a rate equations treatment of the dynamics of levels 3F4 and 3H4.

Abstract

This work presents the spectroscopic characterization of Tm3+doped GaLaS chalcogenide glass and a study on Tm3+:Tm3+ energy transfer. The cross relaxation 3H4,3H6 to 3F4,3F4, responsible for the laser emission at 1.8 µm, and the energy migration 3H4,3H6 to 3H4,3H6 processes are studied in terms of the microscopic parameters of energy transfer Cda and Cdd obtained by the Kushida model of multipolar interaction and by a rate equations treatment of the dynamics of levels 3F4 and 3H4.
