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.
Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise pollution is a major environmental goal for some urban areas.
