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.
能量密度通量的可视化能够为复杂超短脉冲的传播特性提供独特的见解。这种分析方法以前只能通过数值研究来进行,而本文表明它是一种非常有价值的实验诊断工具。通过恢复时空振幅和相位,我们通过实验获得了在非线性克尔介质中由丝状化产生的复杂超短脉冲内的能量密度通量。
