title: Effect of saturation on the diffraction efficiency of holographically recorded gratings in azopolymer films.
abstract: The diffraction efficiency of phase gratings recorded by two s-polarized waves in a polymer is modeled. The molecular orientation distribution along the grating period is seen to become homogeneous as a function of time due to saturation. Experimental data is presented, in agreement with the model.
