中心波长为 9.2 微米的中红外超短脉冲具有振幅和相位特征。这是通过使用光谱相位干涉测量的变体进行直接电场重建来实现的，其中光谱干涉测量已被时域干涉测量所取代，这是一种非常适合红外脉冲的技术。该装置允许同时记录二阶干涉自相关，从而提供对检索的光谱相位的独立检查。
Mid-infrared ultrashort pulses of 9.2-microm center wavelength are characterized in both amplitude and phase. This is achieved by use of a variant of spectral phase interferometry for direct electric field reconstruction in which spectral interferometry has been replaced with time-domain interferometry, a technique that is well suited for infrared pulses. The setup permits simultaneous recording of the second-order interferometric autocorrelation, thus providing an independent check on the retrieved spectral phase.
