An anomalous emission from gallium arsenide during interband absorption of intense picosecond light pulses has been observed experimentally. The emission peaks at a photon energy < Ε °. The emission requires the attainment of a threshold. It correlates with the time evolution of the intensity of the exciting light in the picosecond range.
