Study on Spectroscopy of Yb~(3+) and Er~(3+) Co-doped Phosphate Glasses

The absorption and fluorescent spectra and fluorescent lifetime of Yb3+ and Er3+ co-doped phosphate glass were measured. Some basic properties of spectroscopic properties such as absorption cross section and stimulated emission cross section have been calculated. The effect of P2O5 and Yb2O3 concentrations, alkali metal oxides, alkaline earth metal oxides and OH- on spectroscopic properties of phosphate erbium glasses have been discussed. The Yb3+ and Er3+ co-doped phosphate erbium glass with fluorescent lifetime of 7.5 ms and stimulated emission cross section of 0.8×10-20 cm2 has been achieved in present work. This provides good basis for the future laser experiments.
