摘要
提出了具有非相干抽运的开放的ladder型无粒子数反转激光(LWI)系统模型,给出了定态线性解析解,研究了探测场和驱动场失谐的变化对无粒子数反转激光增益、色散和粒子数差的影响.结果发现,开放的ladder型系统的无粒子数反转激光增益远大于相应的封闭系统;其增益、色散和粒子数差的变化规律与开放的Λ型及简单三能级无粒子数反转激光系统有很大不同.
Abstract
A model of an open ladder-type three level noninversion lasing system is presented in this paper. A steady state linear analytical solution, and the effect of the probe and driving fields detunings varying on the noninversion lasing gain, dispersion and population difference are investigeted. It is found that the open ladder-type system can obtain the noninversion lasing gain much bigger than that obtained in the corresponding closed ladder type system; the variation rule of the gain, dispersion and population difference in the open ladder type noninversion lasing system is much different from those in the open Λ-type and simple three level noninversion lasing systems.
