We report for the first time the second-harmonic generation (SHG) of a fractional-order azimuthal varying vector optical field (FO-AVVOF). SHG process is achieved by a Type-II phase-matching BBO crystal. This nonlinear frequency conversion process reveals the topology multiplication rule and obtains the second harmonic optical field of the ultraviolet wavelength, which may have potential applications in ultraviolet micromachining and all-optical switching.
