            Magnesium Oxide Doped Lithium Niobate Crystal

            Compared with LiNbO3 crystal, MgO:LiNbO3 crystal exhibits its particular advantages for NCPM
            frequency doubling (SHG) of Nd:Lasers, mixing (SFG) and optical parametric oscillators
            (OPOs). MgO:LiNbO3 is also a good crystal for optical parametric oscillators (OPOs) and
            amplifiers (OPAs), quasi-phase-matched doublers and integrated waveguide.

            MgO:LiNbO3 has similar effective nonlinear coefficients to pure LiNbO3 . Its Sellmeier equations
            (for MgO dopant 7 mol%) are:

            no2=4.8762+0.11554/(λ2 - 0.04674) - 0.033119λ2

            ne2=4.5469+0.094779/(λ2 - 0.04439) - 0.026721λ2


            Lithium Tantalate Crystal

            LiTaO3 crystal is also widely used as electro-optic modulator, with NLO and E-O properties
            similar to those of LiNbO3 but higher damage threshold (>500 MW/cm for ns pulsed).
