Physicists exploring use of Blu-ray disc lasers to kill COVID-19, other viruses

A new weapon in the arsenal against the coronavirus may be sitting in your home entertainment console. A team led by physicist Chris Barty of the University of California, Irvine is researching the use of diodes from Blu-ray digital video disc devices as deep-ultraviolet laser photon sources to rapidly disinfect surfaces and the indoor air that swirls around us. Barty, UC Irvine distinguished professor of physics & astronomy, said that such UV light sterilizers would be cheap compared to current medical- and scientific-grade systems and that it’d be possible to deploy them almost anywhere.
