时空维格纳函数是分析飞秒光学器件的强大工具，该器件作用于超短脉冲的空间和时间特征。回顾了这种方法的优点和时空维格纳函数的性质。提出了可用于描述色散一阶器件对任何飞秒脉冲的作用的矩阵形式。该方法用于描述和理解通过脉冲整形器传播的超短光脉冲的行为。充分分析了输出脉冲的光谱空间转换中有限分辨率的后果。
The space–time Wigner function is a powerful tool for the analysis of femtosecond optical devices that act on both the spatial and the temporal features of ultrashort pulses. The advantages of this approach and the properties of the space–time Wigner function are reviewed. The matrix formalism that can be used to describe the action of dispersive first-order devices on any femtosecond pulse is presented. The method is used to describe and understand the behavior of an ultrashort light pulse propagating through a pulse shaper. The consequences of the limited resolution in the spectral-to-spatial conversion for the output pulse are fully analyzed.
