中文摘要	实验研究了圆孔衍射调制下的强激光在克尔非线性介质中的传输特性。观测了小尺度自聚焦效应引起的多细丝形成、单根细丝演化以及细丝之间相互作用过程。结果表明:在非线性传输过程中,衍射调制光束在空间特定位置出现调制增长,导致光束分裂形成多路细丝;单根细丝的强度并非无限增长,而是达到一定值后通过锥形发射释放多余能量,同时与背景光相互作用形成新细丝;相距较近的细丝之间通过干涉相互作用,使其在附近区域形成新的细丝。
英文摘要	The nonlinear propagation characteristics of intense laser with circular aperture diffraction in Kerr medium are stuied by experiments. We experimentally observe the formation of small-scale filaments, the evolution of single filament and the interaction between filaments. Results show that modulation growths take place at particular spatial positions and lead beam breakup into multi-filamentation during nonlinear propagation. The single filament intensity is not growing indefinitely,but to release the excess energy by the cone emitting after reaches a certain value. At the same time, new filaments form owing to the interaction between the background energy and the released energy. The filaments in close proximity through the interference interaction, make new filaments form in their neighborhood.
