TEMPERATURE-DEPENDENT SELLMEIER COEFFICIENTS AND COHERENCE LENGTHS FOR SOME CHALCOPYRITE CRYSTALS.

Abstract

Temperature-dependent Sellmeier equations are useful for determining optical-design parameters of nonlinear optical devices. These coefficients are calculated as a function of temperature for ZnGeP//2, CdGeP//2, and CuGaS//2. Coherence lengths for second harmonic generation as well as its temperature derivative are also presented for these crystals.
