Abstract
We propose an optical method for increasing the number of atoms in a pair of dilute-gas Bose-Einstein condensates. The method uses laser-driven Raman transitions which scatter atoms between the condensate and noncondensate atom fractions. For a range of condensate phase differences there is destructive quantum interference of the amplitudes for scattering atoms out of the condensates. Because the total atom scattering rate into the condensates is unaffected, the condensates grow.
