摘要

本文由光学Bloch方程出发

讨论了二能级系统光谱烧孔中孔宽和孔深与烧孔激光脉冲持续时间的关系.在强场下短脉冲烧孔中

用π脉冲可以得到足够深且宽度小于稳态值的孔.弱场下

孔深与烧孔时间成指数关系.Bloch方程的修正对上述两种条件下烧孔行为的描述无明显影响.以二能级系统光谱烧孔为基础

讨论了永久性光谱烧孔和光子选通光谱烧孔中孔的行为.

Abstract

With the transient solutions of optical Bloch equation

dependences of hole width and depth on the burning pulse duration have been discussed for spectral hole burning of two-level system.With a strong and short π pulse

a deep hole may be burnt.Its width is much narrower than the steady state one predicted by optical Bloch equaion.While burning power density is weak

hole depth will be exponentially dependent on burning time.Modification of the Bloch equation does not significantly affect the results of above mentioned two cases.Based on the behavior of spectral hole burning of two-level system

situations of persistent hole burning and photon gated spectral hole burning have also been considered.
