Relaxation of elementary holographic gratings in As(2)S(3) films at low diffraction efficiencies.
The relaxation processes in As(2)S(3) films related to the self-enhancement effect of holographic gratings with low initial diffraction efficiencies are examined. It is demonstrated that the dark relaxation plays a noticeable role in the self-enhancement.
