Danielle A. Braje, Vlatko Balic, G. Y. Yin, S. E. Harris

摘要:

在光学厚的冷介质中的电磁感应透明产生了一个独特的系统,其中脉冲传播速度可以是小于$c$的数量级,并且光学非线性变得非常大。因此,非线性过程在低光水平下可能是有效的。使用原子系统与三个,独立的通道,我们证明了量子干涉开关的能量密度的$\sim23$光子每$λ^2/(2π)$的激光脉冲的第二个脉冲的1/e吸收的原因。

英文摘要:

Electromagnetically induced transparency in an optically thick, cold medium creates a unique system where pulse-propagation velocities may be orders of magnitude less than $c$ and optical nonlinearities become exceedingly large. As a result, nonlinear processes may be efficient at low-light levels. Using an atomic system with three, independent channels, we demonstrate a quantum interference switch where a laser pulse with an energy density of $\sim23$ photons per $λ^2/(2π)$ causes a 1/e absorption of a second pulse.
