Abstract :
Summary form only given. We study the nonlinear dynamical behavior of the self-focusing of femtosecond pulses both near and above the point at which the pulse effectively undergoes catastrophic collapse. Even for pulses substantially longer than a single optical cycle, our results indicate that the dynamics can only be described by a model that goes beyond the slowly-varying envelope approximation.
