Researchers Use Electric Dipoles to Stabilise Turbulent Laser Beams
Researchers from the Indian Institute of Space Science and Technology (IISST) have developed a novel method to combat the chaotic effects of atmospheric turbulence on laser communication beams.
They used simple polymethyl methacrylate (PMMA), a common plastic, to partially correct a distorted laser beam and restore its statistical order, combining physics with a statistical framework based on geometry.
Their research was published on the preprint server arXiv and is yet to be peer reviewed, marking a significant step toward more reliable high-speed internet.
