Pulses that have been super-broadened by a third-order nonlinearity are frequently used when generating a phase stabilized output. But how can such temporally mangled pulses retain any useful phase information?
We apply a recently developed pulse propagation technique (Pseudospectral Spatial Domain) to study the phenomenon of carrier wave shocking, which occurs when the process of self-phase modulation is accompanied by the generation of harmonics
We model the propagation and interaction of few-cycle pulses using a variant of the finite-difference time-domain (FDTD) method that incorporates a novel pseudospectral technique. This offers a significant advantage over the standard FDTD approach
We model the propagation and interaction of few-cycle pulses using both envelope and FDTD techniques. We show that when solving for a wide class of nonlinear interactions, the carrier phase is essentially irrelevant
