Abstract :
Summary form only given.So far, ultrashort pulse characterization techniques have measured the spatially averaged amplitude and phase of the input beam. For beams exhibiting a significant spatial structure, however, it is desirable to completely spatially resolve the pulses to be characterized. Complex spatial structure can be found, for example, in broadband Kerr-lens modelocked lasers as a consequence of the frequency-dependent mode-size. In this contribution we demonstrate a technique based on spectral phase interferometry for direct electric-field reconstruction (SPIDER) that allows for measurement of the amplitude and phase of an ultrashort pulse at an arbitrary lateral position of the input beam. Only a single measurement is required for the acquisition of the spatially resolved data along one beam axis.
