摘要： From transition-rate-equations and transmission-equations the formulas of threshold power and slope efficiency of an end-pumped laser for a four-level system are deduced. Citing the laser of Er:YAG as an example, we have discussed the differences of laser output characteristics between the three-and four-level systems.
