Broadband visible polarization pulse shaping and pulse characterization by dual-channel and dual-quadrature spectral interferometry — •Tatjana Quast, Patrick Nürnberger, and Tobias Brixner — Institut für Physikalische und Theoretische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg

Polarization pulse shaping is achieved by a two-layer liquid-crystal spatial light modulator in a zero-dispersion-compressor geometry. The pulses are characterized by dual-channel spectral interferometry (SI). Results of polarization-shaped pulses and the measured Jones matrix of the setup are presented.

As an additional pulse characterization technique, dual-quadrature spectral interferometry is introduced. A circularly polarized reference pulse is used to generate the spectral interference pattern with the shaped pulse. By polarization multiplexing, one can extract the in-phase and quadrature fraction of the SI pattern and use them to reconstruct the phase of the shaped pulse. First examples of phase-shaped pulses are shown and an extension to measure polarization-shaped pulses by dual-quadrature SI is presented.
