✦ Synopsis

Some thermomechanical properties such as expansion, transition temperature and hightemperature viscosity of phosphate glasses with different P205 and BaO compositions have been measured. Absorption and fluorescence spectra of the phosphate glasses with different Er 3+ doping have also been measured. The Er 3+ doping concentration with respect to the maximal fluorescence intensity is 0.75 reel %. The attenuation of the fibre at awavelength of 1.53 gm is 12.8 dbm-1. Upconversion of 1.064lam Nd:YAG laser pulses into intense green 547 and 667 nm light in the 0.75 mol % Er3+-doped phosphate glass fibre has been achieved. The output power of the two fluorescence signals of green 547 nm and red 667 nm are 178 and 42 laW, respectively, with an upconversion efficiency of 1.78 x 10-2 % and 4.2 x 10-3 % respectively.

Spectroscopic properties of Er 3+ -doped TeO 2 -WO 3 -Bi 2 O 3 (TWB) glass has been investigated. The transition probabilities, excited state lifetimes, and the branching ratios have been predicted for Er 3+ based on the Judd-Ofelt theory. The lifetime of 4 I 11/2 and 4 I 13/2 level were measured fr
