摘　　要：从描述饱和吸收体调Q的速率方程出发，推导出了实现有激发态吸收的饱和吸收体调Q所需的反转粒子数理论上应满足的条件，并对其进行了讨论与分析，与参考文献的相关叙述相符。The rate equations describing a Q-switched laser system with a saturable absorber are presented. The condition of this kind of Q-switching which should be satisfied by the laser crystal population inversion is deduced. The results from the discussion and analysis are in agreement with the description of references.
