Abstract

We report the complete spatiotemporal characterization of ultrashort light pulses by use of a self-referencing device based on shearing interferometry in the space and frequency domains. The apparatus combines a spatially resolved spectral shearing interferometer with a spectrally resolved spatial shearing interferometer. The electric field as a function of one transverse spatial coordinate and time is obtained from a single experimental trace by means of a direct and fast algebraic phase reconstruction algorithm. The method has been tested in several common laboratory situations.

Main findings

A self-referencing device using shearing interferometry in space and frequency domains is reported for complete spatiotemporal characterization of ultrashort light pulses. The electric field versus one transverse spatial coordinate and time is obtained from a single experimental trace using a direct algebraic phase reconstruction algorithm, and the method was tested in several laboratory situations.
