In this project we have performed both experimental and theoretical studies of nonlinear optical beam interactions in a variety of media. During this reporting period we have 1 extended our set of exact focused-pulse solutions of Maxwells equations in vacuum, 2 discovered a new two-photon resonance in the fullerene C60, 3 measured excited- state cross-sections in protonic-doped bis-benzothiazole 4 developed a nonlinear interferometer which measures phase, as well as magnitude, of certain nonlinear optical susceptibilities, and 5 completed our experimental and theoretical demonstration of the first clear example of a strongly-coupled large polaron.
