Vector beam has spatially dependent polarization state which the polarization direction varies with azimuthal angle
about the beam axis. Such beams can be generated by superposing of optical vortices. Therefore, we have proposed and
demonstrated a scheme to produce vector beam by superposing optical vortices from helical undulators in tandem using
the technique akin to “cross undulator”. In this paper, we present the detail of the scheme and the experimental results.
