Scalar and vector holographic gratings recorded in a photoanisotropic amorphous As(2)S(3) thin film.
Theoretical explanations of the kinetics of scalar and vector holographic gratings are developed, and experimental results are obtained in amorphous AS(2)S(3) thin films. The large nonlinear-optical susceptibilities are evaluated from experimental data in the vicinity of the fundamental absorption edge, and it is found that chi((3))(1111) congruent with 3.2 x 10(-2) esu and chi((3))(1122)/chi((3))(1111) congruent with 0.98.
