Anomalous temperature character of phase conjugation in doped-LiNbO3 crystal

We report here an anomaly that the photorefractive phase conjugate reflectivity increases sharply near 55, 70, and 110 °C in three different doped-LiNbO3 crystals. The anomalous phenomenon is possibly concerned with the structural phase transformation of the crystal, which induces an extra internal...

Description
Summary:We report here an anomaly that the photorefractive phase conjugate reflectivity increases sharply near 55, 70, and 110 °C in three different doped-LiNbO3 crystals. The anomalous phenomenon is possibly concerned with the structural phase transformation of the crystal, which induces an extra internal electric field and enhances the reflectivity.
