Raman Amplification of Matter Waves
arXiv:cond-mat/0311138 · doi:10.1103/PhysRevA.69.041601
Abstract
We demonstrate a Raman amplifier for matter-waves, where the amplified atoms and the gain medium are in two different hyperfine states. This amplifier is based on a novel form of superradiance that arises from self-stimulated Raman scattering in a Bose-Einstein condensate.
