Vector beams (VBs) are widely investigated for their special intensities and polarization
distributions, which are useful in optical micromanipulation, optical microfabrication, optical
communication, and single molecule imaging. To date, nonlinear frequency conversion
(NFC) and manipulation of VBs remain challenging because of the polarization sensitivity of
most nonlinear processes. Here we report an experimental realization of NFC and
manipulation of VBs that can be used to expand the available frequency band. The main …

Vector beams have been extensively investigated in recent years because of their
fascinating vector character across the beam transverse section, which is demonstrated to
be useful for optical micro-manipulation, optical micro-fabrication, optical communication,
single molecule imaging, and so on. To date, it is still a challenge to realize nonlinear
frequency conversion and manipulation of such vector beams because of the polarization
sensitivity in most nonlinear processes. Here, for the first time, to the best of our knowledge …
