    "abstract": "We have expressed the nonlinear optical absorption of a semiconductor in\nterms of its linear spectrum. We determined that the two-photon absorption\ncoefficient in a strong DC-electric field of a direct gap semiconductor can be\nexpressed as the product of a differential operator times the convolution\nintegral of the linear absorption without a DC-electric field and an Airy\nfunction. We have applied this formalism to calculate the two-photon absorption\ncoefficient and nonlinear refraction for GaAs and ZnSe using their linear\nabsorption and have found excellent agreement with available experimental data.",
