Improved resistance to photodamage: The resistance of lithium niobate crystals with high doped MgO (concentration is usually greater than 5mol%) is significantly higher than that of pure LiNbO3 crystals, and can even be increased by two orders of magnitude. This enables MgO:LiNbO3 crystals to maintain stable performance and prolong service life under high-energy laser irradiation.

Reduced photorefractive effect: MgO doping helps to reduce the photorefractive effect of LiNbO3 crystals, i.e., optically induced refractive index changes. This effect is particularly pronounced under blue or green continuous light irradiation, but can be effectively suppressed by doping with MgO, thereby improving the performance stability of the crystal.

Maintain excellent nonlinear optical performance: MgO:LiNbO3 crystals have similar effective nonlinear coefficients to pure LiNbO3 crystals, which means that they perform well in nonlinear optical processes and are suitable for EO applications such as frequency conversion and optical parametric oscillation.

Applications: Q Switch, Phase Modulator, Electro-optic modulators, Optical Parametric Oscillators (OPOs) and Amplifiers (OPAs), Infrared Applications, etc.
