Optimization of a magneto–optic trap using nanofibers |
(a) Counting rate from the fluorescence of cold atoms as a function of the intensity of the cooling beams. The intensity of the re-pumping beam is 35.4 mW/cm2. (b) Counting rate from the fluorescence of cold atoms as a function of the intensity of the re-pumping beams. The intensity of the cooling beam is 33.6 mW/cm2. The detuning of the cooling beam is −11.6 MHz and the axial magnetic gradient is 11.7 Gauss/cm for both cases. |
