University of Osaka Breaks Record with 3,070 Optical Vortices

4/10/2026

Summary

Story summary

The University of Osaka researchers developed a method to generate a world-record 3,070 phase-coherent optical vortices at a peak power of 58 megawatts, addressing limitations in generating multiple vortices and enhancing power output.
Led by Professor Yoshiki Nakata, the team reformulated Laguerre–Gaussian (LG) mode representations into a three-mode Hermite–Gaussian (HG) framework to enable scalable vortex production through multi-beam interference.
The approach could advance optical manipulation, telecommunications, and quantum information processing.
