  Using three-body recombination as the underlying process, we propose a method
of coherently driving an atomic Bose-Einstein condensate (BEC) into a molecular
BEC. Superradiant-like stimulation favors atom-to-molecule transitions when two
atomic BECs collide at a resonant kinetic energy, the result being two
molecular BEC clouds moving with well defined velocities. Potential
applications include the construction of a molecule laser.
