Abstract

The invention relates to near-infrared broadband luminescence erbium and thulium-co-doped bismuthate laser glass and a preparation method thereof. The glass comprises the following components in molar percentage: 53.6-59.8 mol% of Bi2O3, 10-20 mol% of B2O3, 10-20 mol% of SiO2, 10-20 mol% of Ga2O3, 0.8-1.2 mol% of Tm2O3 and 0.2-0.6 mol% of Er2O3. The glass which is prepared by utilizing a melting-cooling method is of glassy yellow and has uniform physical and chemical properties. The glass disclosed by the invention has the advantages of stable thermodynamic property and strong anti-devitrification ability. The Raman vibration spectrum of the glass shows that the strongest vibration peak is in the vicinity of 188-412cm-1. The probability of nonradiative transition of the energy level of rare earth ions is greatly reduced. The radiation bandwidth with the width of 165nm is obtained under pumping of a laser diode with 800nm wavelength and covered on an S plus C plus L wave band. The glass disclosed by the invention is suitable for preparation and application of near-infrared broadband luminescence rare earth ion-doped optical fiber materials.

Description

technical field [0001] The invention relates to laser glass, in particular to a near-infrared broadband luminescent erbium-thulium co-doped bismuthate laser glass and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of optical communication technology and information channel technology, the channel bandwidth of erbium ion-doped silicate glass fiber amplifier (EDFA), which is a key device of wavelength division multiplexing (WDM), has increasingly shown limitations. Expanding the spectrum range of the existing EDFA and selecting a suitable luminescent host material has become an important direction for the development of rare earth fluorescence. The working wavelength range of the existing EDFA is 1530~1600 nm (C+L band). The wavelength range can be broadened to 1440-1600nm (S+C+L band) by introducing thulium ions into erbium monodoped glass. The principle is attributed to the Tm of the thulium ion 3+ : 3 h 4 → 3 f ...
