Lithium niobate (LiNbO 3 ) crystals doped with Fe and Fe:Mn were grown by Czochralski technique. The doping concentrations of Fe and Mn were optimized. Transmission studies reveal broad absorption band centered at 488 nm. The UV cutoff observed for Fe doped LiNbO 3 is 358 nm whereas for Fe:Mn codope
