Phase-coherent matter-wave amplification was
demonstrated using Bose- Einstein-condensed rubidium-87
atoms. A small seed matter wave was created with coherent optical Bragg
diffraction. Amplification of this seed matter wave was achieved by
using the initial condensate as a gain medium through the superradiance
effect. The coherence properties of the amplified matter wave, studied
with a matter-wave interferometer, were shown to be locked to those of
the initial seed wave. The active matter-wave device demonstrated here
has great potential in the fields of atom optics, atom lithography, and
precision measurements.
