摘要
本文从描述饱和吸收体调Ｑ的速率方程出发，推导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，并对其进行讨论与分析。
In this paper we start from the rate equations describing a Q switched laser system with a saturable absorber and finally deduce the condition of this kind of Q switching which should be satisfied by the laser crystal population inversion. We also give a discussion and analyse it. Using this condition, some experiment phenomena can be successfully explained.
