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.
