wavelength, which is valid for T = 25 to 180 °C, for wavelengths λ between 2.8 and 4.8 micrometers. In these equations f = (T − 24.5)(T + 570.82), λ is in micrometers, and T is in °C. More generally for ordinary and extraordinary index for MgO-doped : , with: for congruent (CLN) and stochiometric (SLN).
