The Multiphoton Coherent Hanle Effect
After a lull of several years, a good deal of interest has again been focussed on optical three-wave mixing in atomic vapors. Six years ago Finn and Ward studied dc-electric-field induced optical second-harmonic generation (SHG) in several inert gases. This type of three-wave mixing depends on the mixing of atomic states of opposite parity in a dc electric field. In the second type of atomic three-wave mixing, which has only been reported during the past year, no dc electric field is introduced: instead, the generation occurs as a result of a higher-order (either E2 or M1) multipole moment of an atomic two-photon excitation.
