Stabilizing Turbulent Laser Beams with Electric Dipoles
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.
A team of researchers from IISST combined physics with a statistical framework based on geometry to stabilise a beam of light.
Their research was published on the preprint server arXiv and is yet to be peer reviewed.
This breakthrough is a significant step toward more reliable high-speed internet.
