论文摘要
飞秒激光来源的技术进步要求开发日益精致的特征工具，暗示着丰富现有的可操作非线性相互作用的面板。本文介绍了一种基于光谱干涉仪的新型表征方法，该方法利用了非标准的旋转多普勒效应来产生频率剪切。这种原始方法被称为“电场重建的多普勒效应”，在没有频率转换的情况下提供了光谱剪切，并且具有多个好处，例如在紫外光谱范围内操作的能力或超宽带激光脉冲的表征。
Technological advances in femtosecond laser sources call for the development of increasingly refined characterization tools implying to enrich the existing panel of operable nonlinear interactions. The present paper describes a novel characterization method based on spectral-shearing interferometry which exploits the non-standard rotational Doppler effect for producing the frequency shear. This original approach, called DEER "Doppler Effect for Electric field Reconstruction", provides a spectral-shearing in the absence of frequency conversion and features multiple benefits as for instance the ability of operation in the ultraviolet spectral range or the characterization of ultra-broadband laser pulses.
