| 摘 要： | 本文研究激光理论中使用的两种模型（Haken模型和Louisell模型）的量子起伏。在Haken模型中，激光介质由两能级原子组成，而Louisell模型中是由三能级原子组成。在原子变量绝热消除条件下，研究两种模型在阈值附近或远高于阈值时，输出光谱的振福起伏，并给出两种模型相互逼近的条件。

| Abstract: | We study the quantum fluctuation in two models of the laser, the Haken model and the Louisell model. In the Haken model the laser medium is taken to consistof two-level atoms whereas in the Louisell models it consists of three-level atoms. Theoutput amplitude fluctuation spectrums of two models are studied in the limit where theatomic variables may be adiabtically eliminated, from near threshold to far above threshold. We give conditions to approximate three-level model using two-level model. |
