摘要：

Third-order nonlinear susceptibilities (chi((3))) and nonlinear refractive indices (n(2)) of KDP, BBO and LiNbO3 crystals are measured at the wavelengths of 1064 nm and 532 nm by Z-scan technique. The measurements were carried out at different pulse energies, focusing conditions, and crystals' lengths. It was shown that the increase of phase-matching angle leads to the decreasing of chi((3)) of KDP crystals. The parameters of multi-photon absorption in KDP, BBO and LiNbO3 crystals are determined. The analysis and comparison of experimental and theoretical values of nonlinear susceptibilities are presented. (C) 2003 Elsevier B.V. All rights reserved.
