G. Vemuri et al., SUB-DOPPLER RESOLUTION IN INHOMOGENEOUSLY BROADENED MEDIA USING INTENSE CONTROL FIELDS, Physical review. A, 53(4), 1996, pp. 2842-2845
We propose a scheme for obtaining sub-Doppler resolution for one trans
ition of an inhomogeneously broadened, three-level atomic system, by u
sing an intense control field at the other transition. Analytical and
numerical calculations are presented to delineate the mechanism respon
sible for this sub-Doppler resolution, and quantify the extent to whic
h Doppler broadening can be reduced.
