Magnesium Oxide Doped Lithium Niobate (MgO:LiNbO3)

Magnesium oxide doped lithium niobate has similar properties as lithium niiobate. However, it improves the efficiency of non-critical phase matching (NCPM) frequency doubling of Nd:Lasers and mixing, and optical parametric oscillators (OPOs). The SHG efficiencies is over 65% for pulsed Nd:YAG lasers and 45% for cw Nd:YAG lasers.

Please refer to LiNbO3 for MgO:LiNbO3 properties. Here are the Sellmeier Equations (λ in um and MgO dopant 7 mol%)

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

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