On the evening of March 29th, the Chinese Laser Journal released the "Top 10 Optical Advances in China 2024" with great significance. After multiple rounds of selection by the review committee, "Custom Radial and Angular Quantum Number Spacetime Optical Vortices" was awarded the "2024 China Optics Top 10 Advances Nomination Award" (Basic Research Category).

June 27, 2024 The research achievement "Spatiotemporal optical vortices with controllable radial and." jointly developed by the team of Professor CAI Yangjian from Shandong Normal University and the team of Professor Zhan Qiwen from University of Shanghai for Science and Technology azimuthal quantum numbers was published in the journal Nature Communications. The team successfully prepared high-purity custom radial and angular quantum number spacetime optical vortex intrinsic light fields by integrating digital holography and two-dimensional pulse shaping techniques. This spacetime wave packet exhibits intrinsic transverse orbital angular momentum characteristics and has spacetime phase singularities of distortion and edge dislocation types. By introducing spacetime astigmatism, the spacetime mode conversion between spacetime Laguerre wave packets and spacetime Hermitian wave packets was achieved for the first time, and a complete orthogonal basis in the spatio-temporal domain was constructed. It has laid the foundation for the development of future spatio-temporal structure light fields, optical information coding and communication, complex photon topologies and high-dimensional quantum information technologies. Shandong Normal University is the first institution of this research achievement, and Professors CAI Yangjian and Zhan Qiwen are the co-corresponding authors. Shandong Normal University's selection for this award for the first time not only marks a major breakthrough in the field of light field control, but also fully demonstrates the outstanding strength of our university in the technological innovation of light field control.
