摘要：

Excitonic nonlinearities under nonresonant, quasi-stationary excitation conditions in a GaAs/AlGaAs multiple quantum well structure are investigated. By detuning the pump laser below the lowest heavy hole resonance, we find the first hint of the AC Stark effect in this excitation regime. In another series of experiments we study the light hole to heavy hole relaxation dynamics under ps excitation. Long transition times, exceeding 500 ps, are observed. © 1990.
