Momentum distribution of atoms in one-dimensional Raman cooling with arbitrary coherent population transfer | | Vladimir S. Ivanov

17 Apr 2013 | | Abstract: | We derive an exact and analytical form for the cold-atom momentum
distribution after a large number of one-dimensional (1D) Raman cooling cycles
has been applied. Our result shows that one can select pulse profiles and
lengths rather freely in order to obtain efficient cooling. Our approach takes
into account optical pumping (resonant excitation followed by spontaneous
emission) as an intergral part of the process, and it is noted that it does not
affect the final momentum distribution. Thus subrecoil cooling is possible in
general, and not just for carefully selected combinations of pulse forms and
durations. | | Source: | arXiv, 1304.4914 | | Services: | Forum | Review | PDF | Favorites | |
