Low-light-level nonlinear optics with slow light

Abstract

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 $\sim 23$ photons per ${\lambda }^2/(2\pi )$ causes a 1/e absorption of a second pulse.
