AbstractEr3+-doped silica fibers have demonstrated excellent performance as active optical devices at 1.5 μm. In an effort to identify promising new hosts, we have measureed absorption and emission cross sections for a variety of Er3+-doped glass. Compositions have been identified which have advantages over silica, particularly for pumping with AIGaAs diode lasers at 800 nm.

Effective ~1.47mm and powerful ~1.8mm infrared emissions have been observed in Tm3+-doped bismuth tellurite glasses with low phonon energy under the excitation of 793nm diode laser. Judd-Ofelt parameters W2 (4.65´10-20cm2), W4 (1.15´10-20cm2), and W6 (1.16´10-20cm2) indicate a higher asymmetric and stronger covalent environment in the optical glasses. In 0.5wt% Tm3+-doped sample, the peak emission cross-sections of 3H4®3F4 and 3F4®3H6 transitions are derived to be 2.83´10-21 and 6.13´10-21cm2, respectively, and the maximum gain coefficients of 0.38 and 2.21dB/cm at 1.675 (U-band edge) and 1.856mm wavelengths were anticipated in an ideal status. These results indicate the Tm3+-doped bismuth tellurite glasses are a promising candidate in developing S- and U-band amplifiers.
