摘要

Fluorophosphate glasses doped with different Tm3+ concentrations were prepared. Thermal stability, absorption and fluorescence spectra were measured. J-O parameters and radiative properties were analyzed in detail. The prepared glass possesses high effective emission bandwidth (230 nm), large emission cross section (5.5 x 10(-21) cm(2)) and gain coefficient (0.97 cm(-1)). The optimal 1.8 mu m emission can be obtained when Tm3+ concentration is fixed to 6 mol%. Results indicate that the prepared FP glass is an attractive candidate for potential 2 mu m applications.
