Atom-number amplification in a magneto-optical trap via stimulated light forces



Elizabeth A. Donley, Tara C. Liebisch, Eric M. Blanshan, John E. Kitching


We have decelerated an atomic beam of 87 Rb using a stimulated-emission slowing technique that makes use of a bichromatic standing light wave of high intensity and increased the load rate into a small magneto-optical trap by up to a factor of 20. We performed the slowing over distances of under 1.5 cm with 5.2 mW of total power in the bichromatic beams. We estimate that we achieve a slowing force that is 2.2 x larger than the maximum force achievable by spontaneous emission. The maximum achievable force could be increased in a smaller apparatus
