Raman sideband cooling in the presence of multiple decay channels
journal contribution
posted on 2023-06-08, 08:55 authored by G Morigi, H Baldauf, W Lange, H WaltherWe 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 be described by an effective wave vector. Using this method we determine the rate of heating caused by optical pumping inside and outside the LambDicke regime. On this basis we discuss also the efficiency of a recently proposed scheme for ground-state cooling outside the LambDicke regime [Europhys. Lett. 39 (1997) 13].

Notes
The efficiency of pulsed Raman sideband cooling in the experimentally relevant case of multiple decay and excitation channels is investigated. The rate of heating caused by optical pumping for different localization conditions and the consequences for ground state cooling are investigated.
