MgO-doped congruent Lithium Niobate (MgO:CLN) is widely used in a variety of nonlinear optical processes, while its Sellmeier equation has only been derived from experiments under 200oC. Here we extend the temperature range for the Sellmeier equation study to as wide as 60 oC to 510 oC. This work is important to extend the operation temperature range of MgO:CLN crystal.
