CT63/19-CT64/19The D-TURTLE technique for the characterization of the polarization state of few-cycle pulses has been implemented using ensembles of randomly oriented nanocrystals as non-linear medium. Recording traces for four different field projections we were able to unambiguously determine the polarization state and handedness of few-cycle laser pulses. This approach can be especially interesting in spectral ranges where no bulk crystals are available.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1873-0310https://doi.org/10.1016/j.optcom.2025.131698https://www.sciencedirect.com/science/article/pii/S0030401825002263open access535Ultrafast opticsPolarized few-cycle laser pulsesSHG nanoparticlesÓptica (Física)2209 Óptica2209.10 láseres
