Paper Abstract

Nonlinear optical properties of GaAs/(AlGa)XOY heterostructures using interband excitation by 150 fs laser pulses is reported. A considerable wideband nonlinear response is observed. Mean decay time for nonlinear reflection in heterostructures ranges from 1.5 to 3.5 ps. The shift of the GaAs energy-band structure caused by the high tensions in GaAs/(AlGa)XOY structure is observed.
