Abstract

By monitoring the nonlinear absorption of picosecond laser pulses as a function of lattice temperature, we identify four-photon absorption in bulk InAs. Optical bandgap scaling of this process is consistent with a calculation obtained from fourth-order perturbation theory for allowed-allowed-allowed-forbidden transitions. A model of nonlinear absorption based on laser-induced impact ionization disagrees with the experimental results. (C) 1997 Optical Society of America.
