3. Power measurement via radiation pressure
3.1 Radiation pressure
3.1.1 Reflection of a plane wave by a perfect plane mirror
Consider an ideal monochromatic laser beam propagating in vacuum (plane electromagnetic wave of wavelength λ) which irradiates the plane surface A of a target uniformly at normal incidence.
In the remainder of this subsection, we choose a basic, simplified quantum approach by considering the beam as a constant flux of monoenergetic photons (E = hν) traveling in a direction normal to the plane of the target surface....
