Abstract
A device for measuring a light radiation pressure is provided which includes a torsion balance, a laser, a convex lens, and a line array detector. The laser is configured to emit a first laser beam. The convex lens is located on an optical path of the first laser beam and configured to focus the first laser beam to a surface of the reflector. The line array detector is configured to detect a reflected first laser beam reflected by the reflector. The disclosure also provides a method for measuring the light radiation pressure using the device.

A device for measuring a light radiation pressure, comprising:
- a laser configured to emit a first laser beam;
- a convex lens located on an optical path of the first laser beam and configured to focus the first laser beam to a surface of the reflector;
- a torsion balance comprising a suspended carbon nanotube and a reflector hung on the carbon nanotube;
- wherein the reflector is configured to reflect a focused first laser beam;
- the reflector comprises a film, a first reflecting layer, and a second reflecting layer;
- and the film comprises at least two layers of two-dimensional materials stacked with each other, the film comprises a first surface and a second surface opposite to the first surface, and the first reflecting layer is located on the first surface and the second reflecting layer is located on the second surface;
- and
- a line array detector configured to detect a reflected first laser beam reflected by the reflector.
