Er3+/Yb3+co-doped phosphate are presented, laser glass materials with composition of P2O5-A12O3-BaCO3-KNO3-Li2O-ZnO-Er2O3-Yb2O3 (R-PABKLZ) are presented, in which an optimal molar ratio of 1:4 between Er3+ and Yb3+ was observed for achieving peak laser gain. Furthermore, due to adding 4.7 mol% Li1+and 4.6 mol% Zn2+ ions into the glass, an optimum composition structure based laser material was demonstrated. On the other hand, since the high temperature melting method with changeable temperature control was used, the emission cross section offl uorescence, excited lifetime, and an effective spectral half width reached 9.70 × 10-21 cm2, 8.20 ms, and 53.16 nm, respectively, so that a laser gain (semi×trad) of 103.05 was obtained, which is signifi cantly higher than previously reported results. The manuscript also argued the mechanism of relevant laser gain improvement.
