Measurement of the extraordinary refractive index dispersion in the MIR for Mg:Nd:LiNbO3 crystals by the use of quasi-phase-matching in a random 1D domain structure
We present a method of measurement of the extraordinary refractive index dispersion in MIR for periodically and aperiodically poled nonlinear crystals with unknown or uncertain periods. The method is based on the spontaneous parametric down-conversion and is useful for the crystals with domain structure formed directly in the process of growth by Czochralski technique. As an example we measure the extraordinary refractive index of in-growth poled 2 mol% Mg and 1 mol% Nd doped congruent lithium...[Show more]
