Deskripsi
Polarization parameters of the high harmonics driven by bichromatic circularly polarized pulses are usually assumed near perfect. Here the authors use polarimetry measurement to show that depolarization and ellipticity can arise from symmetry breaking in the ionization of a medium by the ultrashort driving fields.
