啁啾脉冲频域干涉测量技术的扰动重构理论模拟研究

利用啁啾脉冲的频域干涉测量技术，可实现对超快光学瞬态过程的单发诊断，此方法的时间分辨率和单发时间测量范围分别与啁啾脉冲的谱宽和脉冲宽度及光谱仪的工作性能有关。当两束线性啁啾脉冲进入光谱仪后，相同的频谱成分会发生干涉形成频谱干涉条纹，如果其中一束脉冲受到外界扰动的影响，可根据干涉条纹的形状重构出扰动的具体形式。理论研究和数值模拟了由频谱干涉图重构外界附加扰动的过程，模拟结果显示重构出的扰动同附加的真实扰动符合得较好；在频谱记录面有限的情况下，重构出的扰动信号带有强烈的振荡，通过平滑处理有效地抑制了振荡。

Abstract

Using chirped pulse spectral interferometry, single-shot diagnosis of ultrafast optical transient process can be achieved. The temporal resolution is determined by spectral width while the temporal measuring range is determined by pulse width, and they are both affected by the spectrometer′s work performance. After two linear chirped pulse enter into the spectrometer, the same spectral components will interfere to form spectral interference fringes. If one pulse is perturbed externally, the specific shape of perturbation can be reconstructed according to interference fringe patterns. The process of external perturbation reconstruction is theoretically studied and numerically calculated, which shows that the reconstructed perturbation matches well with true perturbation. With finite spectral recording, reconstructed perturbation signal shows strong oscillation, which is suppressed effectively by smoothing treatment.
