Numerical Experiment and Analysis for Characterizing Femtosecond Pulses with SPIDER

对用光谱位相相干直接电场重建法 (SPIDER)测量飞秒光脉冲啁啾特性的光谱位相干涉仪进行了数值模拟 ;对假设具有不同类型啁啾的飞秒脉冲进行光谱位相重构 ,还原出时域脉冲强度包络和位相 。

The numerical analyses have been conducted for characterizing femtosecond laser pulses with the spectral phase interferometry for direct electrical field reconstruction (SPIDER). The spectral phases and amplitudes of the typical femtosecond pulses were reconstructed, as well as the temporal intensity profiles and temporal phases of these pulses were retrieved. The numerical results are in accordance with experimental observations.
