SUMMARY
The discussion focuses on calculating the sideways force exerted on a lens by a laser beam with power P and wavelength λ, when the beam is offset from the optical axis by a distance d. The average radiation pressure is defined as I/c, where I represents the intensity of the laser. Participants suggest using classical mechanics to visualize the problem, likening the scenario to a stream of photons being deflected, and emphasize the importance of the lens's focal length in determining the angle of deflection and the resulting force.
