一个复杂的动力学系统各个变量的弛豫速率可以各不相同，那些快速弛豫的变量比慢速弛豫的变量更快地接近于动力学稳定态，技术上可将快速弛豫的变量用定态处理。因此，系统的动力学特性主要由慢速弛豫的变量决定，而系统的相空间维数也得到降低。这就是绝热消去原理。</div><div><br></div><div> 因此根据此原理对单模均匀加宽激光器分类按场振幅，极化强度和粒子反转三个变量弛豫速率可分为三类：</div><div><br></div><div> A类激光器。这类激光器的极化强度和粒子反转的弛豫速率比场的衰减速率大得多。根据绝热消去原理，激光的动力学行为主要由场的速率方程表述。</div><div><br></div><div> B类激光器。这类激光器的极化强度的弛豫速率比粒子反转的弛豫速率和场的衰减速率大得多。根据绝热消去原理，激光的动力学行为主要由粒子反转和场的速率方程表述。</div><div><br></div><div> C类激光器。这类激光器的三个变量的弛豫速率基本相同，激光的动力学行为由三个变量表述。满足某个条件时，即环腔条件和泵浦强度极高时才可以实现不稳定，这在通常条件下是难以做到的。</div><div><br></div><div> 怎么选择性价比高的激光器<a href="http://b.oecr.com/sell" target="_blank"
