Development of Chalcopyrite Crystals for Nonlinear Optical Applications

Abstract

With recent results for the optical properties of CdGeAs2 the authors now know that it meets the expectations of high nonlinearity, phasematchability and transparency in the infrared from 2 micrometers to 18 micrometers. When growth problems are solved and larger crack free crystals are obtained CdGeAs2 should allow the construction of tunable coherent sources over the entire range from 3 micrometers to 18 micrometers. In addition, it should allow optimum second harmonic generation of a CO2 laser to extend its usefulness to 5.3 micrometers. This report discusses progress in crystal growth of CdGeAs. The index of refraction data and tuning ranges of the crystal are presented, as well as the preliminary nonlinear coefficient measurement results.
