Abstract :
Spectral shearing interferometry provides direct complete real-time information on ultra-short optical signals. Approaches like SPIDER (Spectral Phase Interferometry for Direct Electric field Reconstruction) or SPIRIT (SPectral Interferometry Resolved In Time) rely on the interference of two spectrally sheared pulses. SPIRIT is a passive and self-referenced characterization technique that has shown to be suited to a variety of pulse and experimental conditions. Wideband SPIRIT represents its novel configuration aimed at the measurement of few optical cycle pulses. As shown in this communication, ultra-short pulses of 8 fs and with a low energy (i.e. 0.25 nJ) can be characterized by means of this method.
