我们展示了一种色散扫描（d-scan）脉冲表征方案，采用交叉极化波（XPW）产生作为非线性光学过程。XPW生成是一种退化的四波混频过程，没有相位匹配限制。因此，在d扫描方法中实现它是表征远光谱区域的少周期脉冲的一个很好的选择。我们在近红外区域充分表征了通过空心芯光纤传递的5-10 fs脉冲，并将结果与二次谐波产生（SHG）频率分辨光门控和SHG d扫描表征方法进行了比较。
We demonstrate a dispersion scan (d-scan) pulse characterization scheme employing cross-polarized wave (XPW) generation as a nonlinear optical process. XPW generation is a degenerate four-wave mixing process with no phase-matching limitations. Therefore, its implementation in the d-scan method is a good choice for the characterization of few-cycle pulses in remote spectral regions. We fully characterize 5-10 fs pulses delivered through a hollow-core fiber in the near-IR region and compare the results with the second-harmonic generation (SHG) frequency-resolved optical gating and SHG d-scan characterization methods.
