Title: Energy transfer between two filaments due to degenerate four-photon parametric processes
Keywords: dynamics of nonlinear optical systems, optical instabilities, optical chaos and complexity, optical spatio-temporal dynamics

Abstract: Recently, energy exchange between two filaments crossing at small angle and with power slightly above the critical for self-focusing Pcr was experimentally demonstrated. In this paper we present a model describing the process of this transfer through degenerate four-photon parametric mixing. Our model confirms the experimental results that the direction of energy exchange depends on the relative transverse velocity (incident angle), laser intensity and initial distance between the pulses (relative initial phase). We also investigate the interaction between two collinear filaments in order to explain the filament number reduction for powers close to Pcr in multi-filamental propagation.
