摘要：

We show that (2 + 1)-dimensional Gaussian solitons in media with cascaded second-order non-linearities can be obtained as solutions of first-order differential equations. These solitons have a plane wavefront and belong to a one-parameter family exhibited finally from the real root of a cubic polynomial. Outside this family a large choice of initial conditions exists such that spread of the waves due to diffraction does not occur. (C) 1998 Elsevier Science B.V. All rights reserved.
