We describe a Raman cooling scheme that allows for the simultaneous polarization and cooling of
cesium atoms. Using efficient chirped Raman pulses, cesium atoms confined in a red-detuned
crossed dipole trap are 80 % polarized and cooled to a temperature of 
K. After
cooling, the phase-space density reaches 10-3. We have strong evidence that this value is
limited by multiple photon scattering within the atomic cloud.
