Abstract

Quantum interference in atomic two-photon excitation is exploited for optical demodulation, with phase-sensitive detection at /spl plusmn/12 THz having been achieved. By utilizing the atoms as ultrafast nonlinear mixing elements, a new technique for the comparison of essentially arbitrary frequencies over the range 200-2000 nm is presented.
