2.4 μm fluorescence of holmium doped fluoroaluminate glasses
2.4 μm fluorescence of holmium doped fluoroaluminate glasses
Ho3+-doped fluoroaluminate glass samples were fabricated by melt-quenching. Intense 2.4 μm emission was observed under pumping of a 638 nm laser diode, which was ascribed to the Ho3+:5F5→5I5 transitions. The Judd-Ofelt (J-O) theory was applied to predict the radiative probabilities, radiative lifetimes, and branch ratios of Ho3+ transitions. The emission and absorption cross-sections were calculated, and the gain coefficients determined for a 1 mol% Ho3+ concentration. Our results indicate that Ho3+-doped fluoroaluminate glass has a potential for developing fiber lasers operating at 2.4 μm.

Abstract
Ho3+-doped fluoroaluminate glass samples were fabricated by melt-quenching. Intense 2.4 μm emission was observed under pumping of a 638 nm laser diode, which was ascribed to the Ho3+:5F5→5I5 transitions. The Judd-Ofelt (J-O) theory was applied to predict the radiative probabilities, radiative lifetimes, and branch ratios of Ho3+ transitions. The emission and absorption cross-sections were calculated, and the gain coefficients determined for a 1 mol% Ho3+ concentration. Our results indicate that Ho3+-doped fluoroaluminate glass has a potential for developing fiber lasers operating at 2.4 μm.
