摘要：

We have observed optical precursors by studying propagation of ultrashort optical pulses with a steeply rising and an exponentially decaying trailing edge through a 0.2-mu-m-thick GaAs crystal near the exciton resonance. The appearance of a fast pulse front-the precursor-independent of the detuning with respect to the resonance, was accompanied by a delayed main pulse. The delay of the main pulse varies with detuning in accordance with theoretical predictions.
