SAW Grade Doping Lithium Niobate Wafer MgO Er Fe Doped LT Optical Grade
LiNbO3 is a nonlinear optical grade crystal,MgO-doped LiNbO3 can
effectively increase the damage threshold of the LiNbO3 crystal.
Lithium Niobate(LiNbO3) crystals are widely used in optical
communication, information processing, integrated optics, image
storage, harmonic generation, frequency doubling devices,
parametric oscillations, frequency multiplication of 1064nm lasers
and quadruple frequency phase matching device etc.
