Ultrafast third order nonlinearities of organic solvents.

The third order nonlinear optical parameters of a variety of organic solvents are determined under picosecond and femtosecond laser irradiation. Z-scan measurements have been carried out at 35 ps, 532 nm and at 40 fs, 800 nm, while Optical Kerr Effect studies were performed at 35 ps, 532 nm. The target of the present work is to provide a reference of the nonlinear optical response of various widely used organic solvents under the same experimental conditions and render feasible the direct comparison between their nonlinearities.
