摘要：
Two different host glasses for Er3+, namely, phosphate and borate glasses were prepared. Yb3+ was added as a sensitizer to investigate its effect on the absorption, emission, gain cross sections as well as threshold pumping intensity for generation of laser radiation. Another sensitizer, Cr3+, was added to Er3+. The enhancement of absorption and emission of Er3+ were investigated, in addition, the energy transfer efficiency from Cr3+ to Er3+ was determined from the emission of Cr3+. The threshold intensity for Er3+ laser at 1543 nm is reduced to about 54 times using Yb3+ as a sensitizer.
