Direct radiation pressure measurements for lightsail membranes - Nature Photonics
Simultaneous measurements of the optical force and power exerted by a collimated laser beam on a 50-nm-thick silicon nitride lightsail membrane suspended by compliant micromechanical springs quantify the radiation pressure, enabling further multiphysics studies of radiation pressure forces on macroscopic objects.
