Abstract

We propose a new technique for the measurement of the nonlinear refractive index and two photon absorption coefficients of waveguides and bulk nonlinear materials, The presented method, that was named ”D-scan1”, is nothing but the temporal analogue of the Z-scan2 technique which is based on spatial distortion of gaussian beam.
