Abstract

Abstract Band structure and bonding properties have been investigated in terms of periodic density functional theory (DFT) method, and two-photon absorption (TPA) spectra have been simulated by two-band model for ZnGeP ₂ and AgGaS₂ crystals. It has been predicted that the AgGaS₂ crystal has a wider window of nonlinear transmission, and the laser pumping energy larger than 1.02 and 1.35 eV will lead to deleterious TPA of higher nonlinear effect for ZnGeP₂ and AgGaS₂ crystals, respectively. Electron origin of TPA for them is also discussed.
