This paper reports the high-accuracy Sellmeier and thermo-optic dispersion formulas for the extraordinary ray of 5 mol. % MgO-doped congruent LiNbO3 that provide excellent reproduction of the temperature-dependent quasi-phase-matching conditions in the 0.39-4.95μm and 150-270 μm ranges. We believe that these equations would be highly useful for designing the frequency conversion system based on periodically poled MgO-doped LiNbO3.
