摘要：
Pumping a thin layer of GaAs with a high-power picosecond optical pulse leads to nonstationary edge emission. Experimental data are obtained for the way the time-integrated power spectrum of this emission varies with beam diameter and energy of the optical pump pulse. These data are sufficient to confirm the stimulated nature of the emission, whose duration is in the picosecond time range.
