One-Color Nonvolatile Holographic Recording in Ce:Tb:LiNbO3

Abstract

One-color nonvolatile holographic recording was realized in Ce:Tb:LiNbO3 crystal, which was grown by vertical Bridgman method. The hologram could be erased fast with UV light. High sensitivity (0.21 cm/J at 632.8 nm), high diffraction efficiency (∼50%) and long lifetime (more than 10 years at room temperature) were achieved simultaneously in the same crystal. The deep and shallow centers were revealed by the illumination of UV light. The UV illumination also enhanced the sensitivity by 1.5 times.
