Title: Four-photon parametric mixing and interaction between filaments

Recently energy exchange between two filaments crossing at small angle and with power slightly above the critical for self-focusing P{sub cr} 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)
