采用双色单色场混频的方法，实现了一种长程剪切光谱干涉测量。对具有二次和三次相位畸变的强啁啾脉冲进行了表征。用窄间隙无源标准子产生的同轴双色场测量了2.2 ps（全持续时间为6 ps）的线性啁啾脉冲。高度相干的双色源，即频率稳定激光器，或频率梳中的两个纵向模式，可以预期时间范围的实质性扩展。
A long-time-range spectral-shearing interferometry has been demonstrated by frequency mixing with two-color monochromatic fields. Strongly chirped pulses with quadratic and cubic phase distortion have been characterized. A linearly chirped pulse having 2.2 ps (full duration of 6 ps) has been measured with a coaxial two-color field generated by a narrow-gap passive etalon. Substantial extensions in the time range can be expected with a highly coherent two-color source, i.e., frequency stabilized lasers, or two longitudinal modes in the frequency comb.
