Etj. Nibbering et al., MEASUREMENT OF THE NONLINEAR REFRACTIVE-INDEX OF TRANSPARENT MATERIALS BY SPECTRAL-ANALYSIS AFTER NONLINEAR PROPAGATION, Optics communications, 119(5-6), 1995, pp. 479-484
A fast and accurate method for the measurement of the nonlinear refrac
tive index of transparent materials is presented. The method is applie
d to various solids and liquids. The effective femtosecond response ti
me of the optical Kerr effect in benzene and methanol is determined.
