Abstract

A study was conducted on the light induced beam distortion for intensities up to MW/cm2 level on a series of LN samples using a combination of single-beam Z-scan measurements with CCD recordings of the transmitted beam cross section and the observation of the temporal evolution of the transmittance in a fixed sample position. It was found that in pure and nominally pure cLN, sLN, and Mg-doped cLN with the Mg concentration below the threshold the PR effect was dominant and the Z-scan technique cannot be used in a quantitative way to determine the nonlinear refraction coefficient.
