Doppler effect as a tool for ultrashort electric field reconstruction
Résumé
We present a new variant of spectral-shearing interferometry method for characterizing ultrashort laser pulses. This original approach, called Doppler Effect E-field Replication (DEER), exploits the rotational Doppler effect for producing the frequency shear and provides a spectral-shearing in the absence of frequency conversion enabling operation in the ultraviolet spectral range. Evaluation of the DEER-SPIDER set-up reveals a phase
reconstruction of great reliability. Possible improvements, benefits, and worthwhile prospects of the method are discussed.
