High gain, rare-earth ions co-doped multicomponent phosphate glasses with different doped concentration ratio were prepared and investigated by means of absorption and fluorescence spectroscopy in order to investigate the influence of different doped concentration ratio on material optical properties. The main results showed that there was a strongest absorption at 980nm and saturated at 1530nm when Er3+and Yb3+concentration ratio was 4:1, which is the optimum ratio. It is also demonstrated that reaction and energy transfer mechanism between different ions in rare-earth co-doped system, which is significant for their interest in the fields of optical fiber amplifier and laser.

The influence of the addition of Y2O3 on the structural, spectroscopic, and laser properties of newly prepared Er, Yb-doped strontium-sodium phosphate glass was investigated. While the addition of Y2O3 has a small influence on the absorption spectra and fluorescence lifetime, it has a strong impact on the emission cross-section and on OH− content. The glasses were used as the active medium for diode-pumped laser emitting at 1556 nm. The increase in Y2O3 content leads to a significant 35% increase in laser slope efficiency up to 10.4%, but at the expense of the substantial reduction of the wavelength tunability from 82 to 54 nm.
