Complete pulse characterization: measurements of linear and nonlinear properties

We present a frequency-domain phase measurement technique coupled with a numerical chirp processing of the recorded sonogram to realise a pulse characterisation. Applications to the propagation of ultrashort pulses in linear and nonlinear media are investigated. Calibration of the experimental setup is performed using spectral interferometry technique. Results on linear dispersion glass and Kerr effect in vitreous samples are presented.
