摘要：

The method of two orthogonal beams was used to study nonlinear absorption of CO//2 laser radiation in indium antimonide. A calculation was made to justify the method of determining the two-photon absorption constant from the experimental data. These data revealed that the induced absorption experienced by a probe beam DELTA I//p//r included considerable contributions not only of the two-photon absorption process and of the absorption by nonequilibrium holes created by the pump radiation during this process, but also a contribution of the pump-beam-modified absorption by deep impurity centers.
