Abstract
We have investigated the efficiency of pulsed Raman sideband cooling in the presence of multiple decay and excitation channels. By applying sum rules we identify parameter regimes in which multiple scattering of photons can b e described by an effective wave vector. Using this method we determine the rate of heating caused by optical pumping inside and outside the Lamb-Dick e regime. On this basis we discuss also the efficiency of a recently propos ed scheme for ground-state cooling outside the Lamb-Dicke regime [Europhys. Lett. 39 (1997) 13]. (C) 2001 Elsevier Science B.V.
