Abstract
We present a system of modulation equations that approximate the focus ing of the nonlinear Schrodinger equation in the presence of a small n ormal time dispersion (TDNLS). Since the modulation equations are much easier for analysis and for numerical simulations, they can be used t o get a general picture of the TDNLS focusing. Analytical and numerica l agreement between the modulation equations and the TDNLS is establis hed.
