摘　　要：The trans-spectral manipulation of spatio-temporal structured light,characterized by dynamic inhomogeneous trajectories and a unique nature in the space–time domain,opens myriad possibilities for high-dimensional optical communication in the ultraviolet band.Here,we experimentally demonstrate the high-performance transfer of the spatio-temporal optical Ferris wheel beam from near-infrared to blue–violet wavelengths.Owing to the energy conservation and momentum conservation mechanism,the 420 nm output signal beam accurately retains the spatio-temporal characteristics of the 776 nm input probe optical Ferris wheel beam,facilitated by the 780 nm Gaussian pump beam.The identical multi-petal intensity profiles confirm the successful transfer of spatial characteristics from the input probe to the output signal beams.The fully synchronized rotation velocities and directions of the probe and signal beams demonstrate the precise transfer of temporal characteristics,achieving approximately 98%conversion accuracy.This work enables efficient information transfer across different wavelength bands and offers a promising approach for achieving high-dimensional quantum communication.
