摘要：

The laser properties of Q-switched Cr3+, Yb3+, Er3+ : phosphate glasses have been studied in this work. Rotating prism Q-switched laser at 1.53 mu m was obtained at room temperature in this erbium glass pumped by flash lamp. The best laser properties are realized in the glass with 0.5wt% Er2O3 concentration. The properties include 14.5mJ threshold energy, 9.6mJ maximum laser output and 0.55% slope efficiency. The laser properties of Cr14 was compared with QE-7S produced by Kigre under the same experimental condition. It is deduced from experimental results that the former has a higher threshold energy, maximum laser output and slope efficiency.
