  For experiments that require a quantum system to be in the ultra-cold regime,
laser cooling isan essential tool. While techniques for laser cooling ions and
neutral atoms have been refined andtemperatures below the Doppler limit have
been achieved, present-day techniques are limited toa small class of molecules.
This paper proposes a general cooling scheme for molecules based
onvibrational-state transitions. Superradiance is used to speed up the
two-photon transition. Sim-ulations of this scheme achieve temperatures
comparable to those achieved by existing two-levelschemes for neutral atoms and
ions.
