Doppler effect as a tool for ultrashort electric field reconstruction
arXiv:2003.01421 · doi:10.1364/OL.402935
Abstract
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.
