A strong emission arising from states lying higher in energy than those optically pumped is observed under interband excitation into partially filled Landau levels of a modulation-doped GaAs quantum-well structure in a magnetic field. The intensity of this emission depends quadratically on the excitation power and is strongly influenced by magnetic field through the occupancy of the Landau levels. This effect demonstrates the high efficiency of Auger processes in partially filled Landau levels of a two-dimensional electron gas.
