摘要: We study the interaction of two parallel-launched femtosecond filaments at their fundamental-wave and second-harmonic frequencies in air. Besides Kerr effect within pulse duration, impulsive alignment diatomic molecules filament leads to controllable field-free achievable attraction, fusion, or repulsion filament. The molecular-alignment-assisted is further confirmed by fluorescence intensity variation spectral modulation various molecular revivals.
