| 英文摘要 | in this contribution, we investigate the femtosecond filament interactions in gas by employing hermite-gaussian tem02 mode focused by lens in argon gas by means of numerically evaluating the 3 + 1 dimension nonlinear schrodinger equation. high-resolution spatiotemporal characteristics has been obtained. the tem02 mode laser pulse, which has three lobes in the plane perpendicular to the propagation direction, can form three filaments. in the filamentation region, interaction between the lobes occurs at the trailing parts of the laser filaments which correspond to the blue-shifted supercontinuum generated by self-phase modulation and plasma. we find the energetic spatiotemporal fragments are more inclined to repulsion rather than fusion when close to each other, which may imply that two adjacent single filaments dislike to combine into a big filament in multifilaments. it seems that the phenomenon of repulsion bears no relation to the phase difference between the input subpulses. our finding may help to understand why one cannot supply energy to a single filament by multifilament fusion until to now. |
