摘要:

色散扫描(d-扫描)技术已成为一种简单的实现超短激光脉冲的表征方法。D-扫描轨迹是直观的解释和检索算法,这是快速和强大的已经开发,以获得频谱相位和时间脉冲轮廓。本文对基于二次谐波产生的d扫描技术进行了综述。我们描述和比较最近的实现的表征的几个和多周期的脉冲,以及两种不同的方法记录的d-扫描轨迹在单杆,从而显示了该技术的多功能性。

英文摘要:

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.
