Abstract : This research was concerned with studies of ultrafast processes in condensed matter studied by the various nonlinear optical spectroscopic methods. Work was completed in areas involving: the theory of strong field effects; the separation of fluorescence and Raman scattering; the effects of condensed matter fluctuations on Raman; fully resonant second harmonic generation; Dice effects in chi(squared); analysis of third order responses for rotating dipoles; picosecond studies of molecular reorientation; subpicosecond responses of metal particles to light; and effects of ultrahigh intensity pulses on the Raman spectral shape. Keywords: Picosecond lasers; Resonant molecular optics; Gold particles; Raman scattering.
