Abstract

A self-calibrating fluorescence spectroscopy technique was applied to study cross-relaxation ³H₄, ³H₆ → ³F₄, ³F₄, and energy migration ³H₄, ³H₆ → ³F₄, ³F₄, of the Tm³⁺ Ions doped in the tellurite glass. These glasses are investigated for their use in realization of 2 micron fiber lasers. Micro and macro-parameters of the energy transfer and migration were calculated by the means of the model of phonon-assistant multi-polar interaction and hoping mode. Steady rate equation analysis was used to fit the experimental fluorescence ratio of samples with different concentrations. We found that high-order (dipole-quadrupole) interaction was the dominant mechanism in the energy transfer of Thulium ions.
