A team of researchers at the University of Western Australia has set a record for stability when sending a laser beam across an atmospheric distance. The group describes their laser system in the journal Physical Review Letters.
Ultra-precise lasers can be used for optical atomic clocks, quantum computers, power cable monitoring, and much more. But all lasers make noise, which researchers from DTU Fotonik want to minimize using machine learning.
