对超短激光脉冲在克尔介质中的锥形发射、连续谱产生和光束偏转的时空和远场分布的测量，揭示了具有类X特征的波包的自发形成，从而支持了最近的数值结果[M. Koghesik、E. Wright和J. Moloney，Phys. Rev. Lett。92，253901（2004）]。数值模拟结果与实验数据吻合较好。
Measurements of the spatio-temporal and far-field profiles of ultrashort laser pulses experiencing conical emission, continuum generation, and beam filamentation in a Kerr medium outline the spontaneous formation of wave packets with X -like features, thus supporting recent numerical results [M. Kołesik, E. Wright, and J. Moloney, Phys. Rev. Lett. 92, 253901 (2004)]. Numerical simulations show good agreement with experimental data.
