Sažetak
In femtosecond degenerate four-wave mixing experiments in sodium vapor quantum beats are observed at the wavelength of the third harmonic when the fundamental beams are three-photon resonant. The period of beating which corresponds to the fine structure energy level splitting, does not change with atomic number density, buffer gas pressure or laser intensity. Surprisingly, third harmonic signal is observed only at negative time delays for transient grating pulse sequence. We relate this to the well known interference effect between excitation pathways involving the fundamental and the third harmonic fields which leaves atoms virtually unexcited and prevents formation of population grating.
