Group velocities for 800 nm (e-polarization) and a series of mid-IR wavelengths at 1.8–3.4 μm (both e-polarization
(a) and o-polarization (b)) in 5-mol % MgO-doped LiNbO3 as a function of crystal temperature. All the data were calculated through temperature-dependent Sellmeier equations provided by the HCP Company19.
