摘要：

The transmission of 500 ns pulses through GaAs-AlGaAs heterostructures has been studied as a function of light intensity (0.015 to 50 kW/cm2) and wavelength (810 to 840 nm). The intrinsic exciton absorption (λ=818 nm at 10°K) can be modeled by the sum of a small unsaturable background and a dominant term which saturates as a Bloch resonance with a saturatiom parameter of about 150 W/cm2. © 1979.
