Development of Chalcopyrite Crystals for Nonlinear Optical Applications

Abstract

This final report summarizes recent progress in the growth of three chalcopyrite crystals, CdGeAs2, AgGaSe2 and AgGaS2. Recent applications of these crystals to the generation of tunable infrared radiation has been more actively pursued as a result of a number of important requirements for tunable sources. The treatment includes a discussion of third and fourth harmonic generation. Recent work in AgGaSe2 for infrared generation by mixing is presented as a reprint in Appendix III. Also included in Appendix IV is a preprint of a paper describing a new model for the calculation of second order nonlinear susceptibilities. The Bond Orbital Model is a physically descriptive model which should prove useful for estimating nonlinear properties of new semiconducting crystal compounds. The accomplishments of this program have been the growth and characterization of the chalcopyrite crystals CdGeAs2, AgGaSe2 and AgGaS2 and their application to the generation of infrared radiation by second, third and fourth harmonic generation, and by mixing over the spectral range from 1 micrometer to 18 micrometers.
