Abstract

A series of vanadium-doped lithium niobate (LN:V) crystals has been grown and their photorefractive properties were investigated. For $0.1\text{\hspace{0.17em} mol.}\%$ V-doped ${\mathrm{LiNbO}}_3$, a fast photorefractive response of $160\mathrm{ms}$ was obtained with a $351\mathrm{nm}$ laser and a total light intensity of $583\mathrm{mW}/{\mathrm{cm}}^2$. The measurements of the x-ray photoelectron spectrum and electron paramagnetic resonance show that ${\mathrm{V}}^{3+}$, ${\mathrm{V}}^{4+}$, and ${\mathrm{V}}^{5+}$ ions exist in these LN:V crystals. ${\mathrm{V}}^{3+}$ and ${\mathrm{V}}^{4+}$ ions correspond to the 420 and $475\mathrm{nm}$ absorption peaks, respectively. The fast photorefractive response and high sensitivity indicate that LN:V is a suitable candidate for UV photorefractive applications.
