Abstract: The increase in the absorption of light by a semiconductor (when the light photon energy is somewhat smaller than the semiconductor bandgap or equals it) in the presence of a strong light wave (for which the semiconductor is transparent) has been investigated. The possibility of designing novel light detectors for measuring the energy parameters and spatial and temporal characteristics of high-power IR laser radiation is demonstrated.
