多普勒展宽介质中EIT共振的窄化
Narrowing of EIT resonance in a Doppler Broadened Medium
摘要：
本文导出了多普勒展宽系统中EIT共振线宽的解析表达式。它示出在这里，对于相对较低的强度的驱动场的EIT线宽是成比例的强度的平方根，是独立的多普勒宽度，类似于由Feld和Javan的激光诱导线变窄效果。在高强度的限制下，我们恢复了通常的功率展宽的情况下，EIT线宽是成正比的强度和成反比的多普勒宽度。
英文摘要：
We derive an analytic expression for the linewidth of EIT resonance in a Doppler broadened system. It is shown here that for relatively low intensity of the driving field the EIT linewidth is proportional to the square root of intensity and is independent of the Doppler width, similar to the laser induced line narrowing effect by Feld and Javan. In the limit of high intensity we recover the usual power broadening case where EIT linewidth is proportional to the intensity and inversely proportional to the Doppler width.
