Two-color nonvolatile holographic recording in Bridgman-grown Ru:LiNbO_3 crystals

摘要

The Ru:LiNbO_3 crystal with the size of φ25mm × 70 mm was grown for the first time by the vertical Bridgman method from the congruent melt doped with a high concentration of 0.05 wt% RuO_2. The as-grown crystal was dark brown in color without obvious colo
