论文摘要
色散扫描（D-SCAN）技术已成为超短激光脉冲的一种简单到实现的特征方法。 D-scan轨迹直观地解释和检索算法，这些算法既快速又健壮，以获得光谱阶段和时间脉冲曲线。在这里，我们根据第二次谐波生成对D-SCAN技术进行了审查。我们描述并比较了最新的少数和多周期脉冲表征的实现，以及单次记录d-scan痕迹的两种不同方法，从而显示了该技术的多功能性。
The dispersion scan (d-scan) technique has emerged as a simple-to-implement characterization method for ultrashort laser pulses. D-scan traces are intuitive to interpret and retrieval algorithms that are both fast and robust have been developed to obtain the spectral phase and the temporal pulse profile. Here, we give a review of the d-scan technique based on second harmonic generation. We describe and compare recent implementations for the characterization of few- and multi-cycle pulses as well as two different approaches for recording d-scan traces in single-shot, thus showing the versatility of the technique.
