Zusammenfassung: 
Sr0.61Ba0.39Nb2O6:Ce exhibits pronounced dichroism which is strongly correlated with the cerium concentration. This property triggers effective hologram recording with mutually orthogonal polarized writing beams via self-diffraction. We measure the saturation diffraction efficiency, using an extraordinarily polarized readout beam, versus the polarization of the recording beams. The experimental results are compared to straightforward theoretical models based on linear dichroism including self-diffraction. We show that the saturation diffraction efficiency is strongly enhanced by self-diffraction effects.
