摘要：

The coherent cyclotron transients generated upon femtosecond interband photoexcitation of GaAs are studied under different magnetic-field configurations. By varying the excitation wavelength, we are able to discriminate between contributions to the THz emission due to ballistic transport and instantaneous inter-Landau level polarizations.
