Abstract

Tm3+-doped Li2O-SrO-ZnO-Bi2O3 (LSZB) glasses that are suitable for optical amplifier applications have been fabricated through the conventional melt-quenching method, and the spectroscopic properties of Tm3+ in the glasses were characterized. The density, the refractive indices, the optical absorption, the Judd–Ofelt parameters Ωt, and the spontaneous transition probabilities of the glasses were measured and calculated. Using the least-squares fitting method, the Judd–Ofelt intensity parameters Ωt were found to be Ω2=4.29X10-20cm2, Ω4=1.16X10-20cm2, and Ω6=0.84X10-20cm2. Intense 1.47-μm fluorescence was observed in these glass systems under 785-nm excitation. The emission peak from the Tm3+: 3H4→3F4 transition locates around 1.47-µm with a bandwidth is ~112 nm, which is significantly wider than the bandwidth of Tm3+-doped ZBLAN at 80nm but smaller than that in KBG glasses. The results indicate that Tm3+-doped LSZB glasses is a promising host material for applications in optical amplifiers.
