摘要：

This paper presents an analysis of the green emission of Ho3+ (S-5(2) --> I-5(8)) under excitation around 750 and 840 nm in the Ho3+, Yb3+:YAlO3 system. The up-conversion process in the case of pump around 750 nm is a combination between a looping mechanism based on excited state absorption from the I-5(7) level and an avalanche mechanism based on excited state absorption from the I-5(6) level.
