Nonlinear optical studies of rydberg atoms using degenerate four-wave mixing
Jenny Lam, R. A. McFarlane, Duncan G. Steel
The spectral behavior of the third order nonlinear optical response of atomic sodium was studied. As a result, new kinds of frequency domain spectroscopy techniques were developed: nearly degenerate four-wave mixing, polarization nearly degenerate four-wave mixing, frequency domain three-state spectroscopy, and nonlinear Hanle effect in degenerate four-wave mixing. These techniques have provided new information on several areas of collision physics including: dephasing collisions (spectral broadening and frequency shift), velocity changing collisions, state changing collisions, and spin-flip collisions.
