Light-Induced Absorption and Holographic Recording in Pr:LiNbO3

Light-Induced Absorption and Holographic Recording in Pr:LiNbO3

With ultraviolet illumination, we have found a broad UV-induced absorption in the blue and some involvement of Pr ions in Pr:LiNbO3. Transient and stable absorption induced by UV illumination was analyzed at 457, 514, and 633 nm and could be explained by hole trap centers and iron ions. We also stud...

Zusammenfassung:With ultraviolet illumination, we have found a broad UV-induced absorption in the blue and some involvement of Pr ions in Pr:LiNbO3. Transient and stable absorption induced by UV illumination was analyzed at 457, 514, and 633 nm and could be explained by hole trap centers and iron ions. We also studied the effects of UV illumination and boundary conditions during holographic recording in the visible. In ultraviolet-gated short-circuit holographic recording, we obtained a high sensitivity and a high diffraction efficiency. KCI Citation Count: 3
