LiNbO3 is widely used as electro-optic modulators and Q-switches for Nd:YAG, Nd:YLF and Ti:Sapphire lasers as well as modulators for fiber optics.
LiNbO3 and MgO:LN Pockels Cell has high transmission in the very wide wavelength range from 420 - 5200 nm.
MgO:LiNbO3 EO Crystal have similar electro-optic properties to LiNbO3 Crystal but with higher damage threshold.
