We study enhanced cooling of atoms within an optical cavity using feedback and a time-dependent pump source. The two approaches operate on the same principle by increasing the modulation of the optical potential induced by atomic motion in the cavity. We show that cooling time can be reduced by up to two orders of magnitude over conventional cavity cooling.
