A scheme based on the Cranck-Nicholson model has been realized in Matlab code and used to simulate the intensity propagation of various temporal pulse shapes through optically nonlinear materials. The differential equations associated with three- and five-level systems were solved numerically in each point over the active time-space grid. Instantaneous two-photon absorption and dynamic multilevel systems, one at the time, or in combination, can be used to model material responses. A typical Rayleigh length was 0.5 mm. and a pulse length up to a few nanometers for sample lengths of typically 2 mm. (C) 2002 Elsevier Science B.V. All rights reserved.
