title: Spatio-temporal and -spectral coupling of shaped laser pulses in a focusing geometry.
abstract: The spatio-temporal coupling of shaped laser pulses is measured using scanning SEA TADPOLE as a function of propagation distance through the focal region of a plano-convex lens. A double pulse sequence is measured to have a gradually changing spectral phase across the beam front as a function of propagation distance. When a sinusoidal spectral phase is applied to the shaper a saw-tooth spectral amplitude is measured across the beam front before and after the focal plane of the lens. The measured spatio-spectral phase and amplitude for these two common pulse shapes are consistent with the predictions of a theoretical model.
