Longitudinal-Transverse Dynamics of Two-Component Pulses in Uniaxial Crystals

摘要

Based on the Ritz-Whitham variational principle, a set of equations is derived that describe the longitudinal-transverse dynamics of parameters of an electromagnetic pulse whose ordinary component is a quasi-monochromatic pulse and whose extraordinary component is a videopulse. The critical parameters that determine the pulse stability relative to self-focusing are determined.
