Abstract
The spatiotemporal evolution of an ultrashort pulse pair is investigated numerically by solving the coupled Maxwell-Bloch equations without invoking the slowly-varying envelope approximation and rotating-wave approximation. For each pulse, the temporal effect causes the breakup while the transverse effect leads to instability and reshaping. The split pulse pair always remains out-of-phase or in-phase depending on the relative phase of the incident pulse pair. When the incident pulse pair is in-phase, fusion can appear in the ultrashort regime under proper parameter conditions.
