摘要：

We have studied the influence of cascaded second-order effects on the spectral density of a second-harmonic pulse generated in thin KDP and β-barium borate crystals by an intense femtosecond pulse. A noticeable evolution of spectral density is recorded for any value of phase mismatch. This evolution is in good agreement with the solution of the nonlinear propagation equation and allows a simple direct measurement of the effective susceptibility of the studied crystals. © 1998 Optical Society of America.
