摘要：
We investigate the effect of rapidly varying perturbations on the initial stage of the three-dimensional propagation of ultrashort pulses through a nonlinear dispersive medium, in the limit and beyond the slowly varying envelope approximation. We have found a space-time coupling effect which distorts and reduces the range for which sidebands appear on far-field and temporal spectrum. (C) 1999 Published by Elsevier Science B.V.
