Characterization of the diffraction behavior of femtosecond pulses by hard-edge circular apertures via STARFISH technique


The spatio-temporal characterization of the electric field of an ultrashort laser pulse after passing through a diffractive optical element has been done. The expressions derived for the total diffraction field in the time and spectral domain are validated using spatially resolved spectral interferometry assisted by an optical fiber coupler (STARFISH).
