We present a new simulation code able to simulate the entire propagation of a laser pulse, from the amplifiers up to the focusing stage. This algorithm has some new features. It computes the threedimensional optical propagation equation using no approximation other than the picosecond one. Its stability has been carefully studied, and it can be applied to any geometry. This is a great improvement in that up to now, only the cylindrical geometry was accessible with accuracy. We also present a method, using the fast Fourier transform, for evaluating with a high accuracy the Fresnel distribution of a focused laser pulse. The advantages provided by this algorithm are its rapidity and its close relation to physical understanding of the focusing phenomena.
