Development of chalcopyrite crystals for nonlinear optical applications. Final report, 30 Jun 1972-31 Oct 1974
This final report summarizes recent progress in the growth of three chalcopyrite crystals, CdGeAs$sub 2$, AgGaSe$sub 2$, and AgGaS$sub 2$. Recent applications of these crystals to the generation of tunable infrared radiation have 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 AgGaSe$sub 2$ 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 CdGeAs$sub 2$, AgGaSe$sub 2$, and AgGaS$sub 2$ 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 to 18 $mu$.
