Influence of the absorption grating on the diffraction efficiency in thick photovoltaic media in transmission geometry under non linear regimes

With simultaneous phase and absorption gratings, we calculated the contribution of the absorption grating to the total diffraction efficiency in thick samples (~ 1 cm) of iron doped LiNbO3. We considered transmission geometry, with an applied field of 5 kV/cm. First we solved numerically the set of...
