Abstract
The mechanism of the nonlinear photo-carrier generation in low-temperature-grown GaAs by 1.5 μm pulses was investigated by a double pulse experiment. The effect of intermediate excitation on the photo response was distinctly observed. Moreover, the effect was found to be largely coherent, contrary to the proposed model.
