能量密度通量的可视化提供了对复杂超短脉冲传播特性的独特见解。这种分析，以前降级为数值研究，在这里被证明是一个宝贵的实验诊断工具。通过反演时空振幅和相位，实验得到了非线性克尔介质中丝化产生的复杂超短脉冲内的能量密度通量。
Visualization of the energy density flux gives a unique insight into the propagation properties of complex ultrashort pulses. This analysis, formerly relegated to numerical investigations, is here shown to be an invaluable experimental diagnostic tool. By retrieving the spatio-temporal amplitude and phase we experimentally obtain the energy density flux within complex ultrashort pulses generated by filamentation in a nonlinear Kerr medium.
