Abstract
We report measurements of the spectral dispersion and the magnitude of three‐photon absorption in Al0.18Ga0.82As for photon energies between one half and one third the band gap and show that a two‐parabolic‐band model is valid in this material. These results indicate that there is a limited spectral range below half the band gap in AlGaAs (and presumably all semiconductors) in which the bound electronic optical nonlinearity can be used without significant multiphoton absorption.Keywords
