The laser properties of Q-switched Cr3+,Yb3+,Er3+:phosphate gl asses have been studied in this work.Rotating prism Q-switched laser at 1.53μm was obtained at room temperature in this erbium glass pumped by flash lamp.The b est laser properties are realized in the glass with 0.5wt% Er2O3 concentrati on.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 pro duced by Kigre under the same experimental condition.It is deduced from experime ntal results that the former has a higher threshold energy,maximum laser output and slope efficiency.
