| 中文摘要 | nonlinear x-wave formation at different pulse powers in water is simulated using the standard model of nonlinear schrodinger equation (nlse). it is shown that in near field x-shape originally emerges from the interplay between radial diffraction and optical kerr effect. at relatively low power group-velocity dispersion (gvd) arrests the collapse and leads to pulse splitting on axis. with high enough power, multi-photon ionization (nipi) and multi-photon absorption (mpa) play great importance in arresting the collapse. the tailing part of pulse is first defocused by mpi and then refocuses. pulse splitting on axis is a manifestation of this process. double x-wave forms when the split sub-pulses are self-focusing. in the far field, the character of the central x structure of conical emission (ce) is directly related to the single or double x-shape in the near field.
