Abstract
Quantum interference in the rate of two-photon excitation of the 6S(1/ 2)-->6P(3/2)-->6D(5/2) transition in atomic cesium is exploited to dem onstrate phase-sensitive frequency demodulation for an optical interva l of +/-12.5 THz. By thus using atoms as ultrafast nonlinear mixing el ements, we suggest and analyze a new avenue for absolute comparisons o f a dense set of frequencies over the range of 200-2000 nm.
