Abstract

We presented the calculation of nonlinear third order susceptibility focused on Two-photon absorption phenomena (TPA) on bulk crystal semiconductors. Our calculation considers the longitudinal gauge approximation to the interaction field, the non-local part of the crystal potential and the scissor operator as correction to LDA energies calculations.
