Temperature and wavelength dependent refractive index equations for MgO-doped congruent and stoichiometric LiNbO3 [link]Paper  doi  abstract   bibtex   
We present wavelength- and temperature-dependent refractive index equations for 5% MgO-doped congruent PPLN and for 1% MgO-doped stoichiometric PPLN crystals valid for a wide spectral and temperature range. The dispersion equations were derived from quasi-phase-matched nonlinear interactions with these two crystal compositions in the near and mid-infrared. The results show a good agreement with previously published frequency conversion experiments.
