Radially polarized (RP) and azimuthally polarized (AP) light beams draw attention because of advantages such as breaking the diffraction limit by possessing a longitudinal electromagnetic field component in the focus . Meanwhile, intense laser pulses with only few optical cycles gained high importance in the generation of isolated attosecond pulses, or in the case of particle acceleration [2,3]. Combining the vector beam properties with the few-cycle pulse duration can pave the way for new applications, like generating RP or AP isolated attosecond pulses . Amplification of the ultrashort pulses generally limits the available shortest pulse duration, which can be overcome by utilizing post-compression techniques, such as noble gas filled hollow-core waveguides, thin plates or multipass cells. It was shown numerically and experimentally, that the post-compression in a multipass cell is a promising and efficient approach for high average power pulses .
