Abstract
The applications of the new interferometric techniques to the measurement of nonlinear refractive index are summarized in this paper. Developed methods are based on dispersion and shearing interferometry and allow to perform the direct phase measurements in the near field. The majority of the limitations of traditional interferometers have been eliminated in these schemes. At the same time, the benefit of using these methods comparable to currently used is shown for the cases of complicated dependence of the refractive index on the intensity and when the response time of nonlinearity is comparable with the laser pulse duration.
