Abstract

The measurements of nonlinear refractive indices and third-order susceptibilities responsible for self-action effects in nonlinear-optical crystals (KDP, KTP, BBO, LiNbO3) in various spectral ranges (1064 and 532 nm) were carried out by the Z-scan method. It was obtained that investigated media (excepting KTP crystal λ=1064 nm) had self-focusing properties. The significant values of nonlinear losses were recorded at λ=532 nm. The analysis and comparison of experimentally and theoretically obtained values of nonlinear susceptibilities are given. The angular and polarization dependencies of Kerr nonlinearities were analyzed.
