Narrow-line Doppler cooling of strontium to the recoil limit

Experimental results on narrow line cooling of strontium atoms are presented. Doppler cooling is performed on the /sup 1/S/sub 0/-/sup 3/P/sub 1/ intercombination transition at 689 nm resulting in temperatures near the recoil limit in a one-dimensional (1-D) optical molasses. Frequency chirp cooling is successfully demonstrated as a means of expanding the cooling range.
