Superradiance in a Bose-Einstein condensate in the short-pulse regime
Abstract
We have studied the properties of superradiance in a cigar-shaped Bose-Einstein condensate (BEC) of ^87Rb atoms using a pump pulse with durations shorter than the inverse of the one-photon recoil frequency. In this regime we found that the superradiant scattering pattern of the condensate was dramatically altered due to Kapita-Dirac diffraction involving the pump light and the scattered light (end-fire mode) of the condensate. This phenomenon demonstrates that the photons in the end-fire mode can stimulate further scattering even though they leave the condensate about ten orders of magnitude faster than the recoiling atoms.
