Abstract
Tm3+-doped barium gallo-germanate glasses were fabricated, and two efficient and easy-operated dehydration processes were conducted in the fabrication processes. Spectroscopic properties were obtained at room temperature, Judd–Ofelt parameters and laser parameters (absorption and emission cross-section, gain coefficient) were calculated using the McCumber (MC) theory and Fuchtbauer–Ladenburg (F–L) formula. Results indicate that barium gallo-germanate glass will be a good glass host for the 2.0-μm Tm3+-doped optical fiber laser. Factors influential to the population inversion of the 3F4 level to the total rare-earth ions of the potential 2.0-μm Tm3+-doped optical fiber laser were analyzed using the rate equations.
