摘　　要：Dear Editors,Energy exchange between two filamentary pulses was demonstrated in several experiments [ 1-4], and the energy- transfer direction depends on the time delay between filamen- tary pulses, the initial chirp, the laser intensities, the location, the crossing angle and the relative polarization. However, the understanding of the physical mechanisms of energy ex- change in literatures are different and puzzling, including the impulsive Raman nonlinear response of the molecules [1], the plasma-mediated forward stimulated Raman scattering [2], the traveling plasma grating [3], and the classical two beam coupling model [4].Dear Editors,Energy exchange between two filamentary pulses was demonstrated in several experiments[1-4],and the energytransfer direction depends on the time delay between filamentary pulses,the initial chirp,the laser intensities,the location,the crossing angle and the relative polarization.However,the understanding of the physical mechanisms of energy ex-
