Megawatt structured light arrives with 3,070 optical vortices in one array

Phys · · 456 words · By University

Researchers at the University of Osaka have developed a method to generate a megawatt-class optical vortex array with 3,070 phase-coherent vortices, achieving a peak power of 58 megawatts. The approach uses a reformulated HG–LG mode-conversion framework and a compact DOE–SPP–4f Fourier system, enabling scalable structured-light generation with applications in photonics and laser processing.
