A set of rate equations is developed for the operation of an ir laser in passive Q-switching. This set of equations includes the effect of rotational hole burning in the saturable absorber and the high gain and nonuniform losses in the cavity of the laser. Using these equations a set of criteria is developed, which states conditions on the parameters of the laser and the absorber that have to be fulfilled in order that the laser-absorber system should operate in pulses. Experimental verification of the criteria is given. The three phases of the operation of the laser (cw, pulses, and zero output) are depicted on a phase diagram that emphasizes the dependence of the operation on the parameters of the laser and the absorber.
针对红外激光器在被动调Q运转情况推导了一组速率方程。这组方程考虑了可饱和吸收体中的旋转烧孔效应以及激光器腔内的高增益和非均匀损耗。利用这些方程得出了一组判据,该判据给出了激光器和吸收体参数应满足的条件,以便激光 - 吸收体系统能以脉冲方式运转。给出了这些判据的实验验证。激光器运转的三个阶段(连续波、脉冲和零输出)在一张强调运转对激光器和吸收体参数依赖性的相图上得到了描绘。
