MgO:LiNbO3 Crystal Description

Pure LiNbO3 (LN) is an ideal choice for various optical devices. MgO: LiNbO3 Crystal has a higher optical damage threshold, which can solve the problem of low threshold damage for pure LiNbO3 crystal. MgO doping has played an important role in LiNbO3 and has shown an increased threshold laser beam strength by 100 times.

MgO:LiNbO3 Description

MgO: LiNbO3 has a similar effective nonlinear coefficient to pure LiNbO3. Its Sellmeier equations (for 5 mol% MgO dopant) are (λ in µm):

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

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