Abstract

This paper analyzes the lasing performance of Yb:YAG and Nd:YAG laser. The authors deduced the formulas used here on lasing threshold and slope-efficiency. The effective reflectivities of plane-plane laser cavity are 90% and 99% respectively. It is obtained that the crystal length is about 0.2 cm corresponding to the minim threshold for 6.5 at% Yb:YAG. With the increasing of the crystal length, the threshold for Nd:YAG laser goes to stable. It is also deduced that the slope efficiency of Yb:YAG is twice as much as that of Nd:YAG, and the output power of Yb:YAG laser is possibly higher than that of Nd:YAG when the input power is properly high.
