摘要：

We report the observation of optical gain in the transparency region of gallium arsenide highly excited by femtosecond pulses just below the excitonic resonance. We find a very good agreement of the pump-probe spectra with a model based on the fifth-order development of the time-dependent density operator. [S0031-9007(97)04540-7].
