摘要：

A study of the Ho3+ 2-mu m laser emission in Gd3Ga5O12 using Yb3+ and Tm3+ ions as sensitizers is presented. We show by quantum-yield measurements that up-conversion energy losses are weak in the triply doped crystal. Models that describe the excited-state dynamics for both up- and down-conversion processes are given.
