强吸收多普勒展宽介质中相干控制透明和远非简并参量增益

Coherence-controlled transparency and far-from-degenerate parametric gain in a strongly-absorbing Doppler-broadened medium

Thomas F. George, A. K. Popov

摘要:

在非简并双Lambda多普勒展宽介质中,当反斯托克斯辐射的无反转增益大于振荡阈值时,将伴随斯托克斯增益。数值模拟应用于二聚钠蒸汽的结果说明。示出了通过介质和驱动辐射参数的微小变化控制的从吸收到增益的光学切换,所述驱动辐射参数处于小于每个分子一个光子的水平。相关视频/音频剪辑见:A.K. Popov,S.A. Myslivets和T.F.

英文摘要:

An inversionless gain of anti-Stokes radiation above the oscillation threshold in an optically-dense far-from-degenerate double-Lambda Doppler-broadened medium accompanied by Stokes gain is predicted. The outcomes are illustrated with numerical simulations applied to sodium dimer vapor. Optical switching from absorption to gain via transparency controlled by a small variation of the medium and of the driving radiation parameters which are at a level less than one photon per molecule is shown.
