Experimental apparatus. Spider thread length: . The incident polarization on the plate is determined by the orientation of the first plate. The incoming beam is retro-reflected by the mirror .
(Color online) Angle of rotation vs time for left-handed (L), linear (Lin), and right-handed (R) polarized incident photons for an output laser power of . The solid lines are parabolic fits of the experimental data.
(Color online) Angular acceleration of the plate vs the optical power of the laser beam for left- (L) and right- (R) handed incident polarization. The solid lines are linear fits of the experimental data for the two polarizations.
A -thick half-wave plate, floating on is inserted in (a) a circularly polarized traveling wave system above an absorbing medium, (b) the no-node mirror system. Note that, in this case, the standing wave is for instance a left-handed helicoidal wave above the plate and right-handed helicoidal wave under the plate. The photographs show the birefringent plate in both systems.
