Book excerpt: The time delayed four wave mixing technique using very wide band 300 angstroms laser noise has been applied to study nile blue and relaxation times in the low femtosecond regime have been measured as well as quantum beats which reveal vibronic structure. Relaxation in multi level systems has been analyzed and applied to the results in nile blue. Attosecond beats in K vapor have been observed and analyzed. Interference effects have been observed in Na vapor which allowed the erasing of photon echo information. Linear and nonlinear effects of local field corrections have been analyzed and applied to third harmonic generation and selective reflectivity. The local field corrections are found to effect both the line shape and the response frequency. When the input fields are intense an analysis which goes beyond the slowly varying amplitude approximation reveals that the transverse profile of the input beam is modified.
