开放的Ladder型无反转激光系统中的传播效应

PROPAGATION EFFECT IN AN OPEN LADDER-TYPE INVERSIONLESS LASING SYSTEM

利用开放的Ladder型无反转激光系统模型,通过数值计算结果,分析了无Doppler效应和有Doppler效应两种情况下,传播效应对无反转激光增益,探测场和驱动场Rabi频率及能级粒子数布居的影响,同时还研究了在特定距离处,无反转激光增益与介质入口处的驱动场Rabi频率和Doppler展宽的关系.

Using the model of an open Ladder type inversionless lasing system, we analyze the affections of propagation effect on the inversionless lasing gain, Rabi frequencies of probe field and driving field, and the populations by the numerical calculation results for the both cases with and without considering the Doppler effect. We also study the relationships between the inversionless lasing gain at a specific distance and the Doppler broadening width, Rabi frequency of the driving field at the entrance of the medium.
