The multiphoton ionization probability has been calculated as functions of wavelength and electric field intensity for a number of semiconductors and insulators using three different theoretical models. Although there is a large amount of disagreement among available experimental data, the values of two-photon absorption coefficients calculated by Keldysh treatment come closest, while the Basov formula over-estimates and the Braunstein formula underestimates. Surprisingly, Keldysh formula also predicts the absolute values and the wavelength dependence of the one-photon absorption coefficient (absorption edge) extremely well for direct gap semiconductors.
