摘要
We report the observation of spectral hole burning exclusively due to the nonequilibrium electron population in a nondegenerate pump-test configuration. The rapid redistribution, of electrons as well as the other features of the differential absorption spectra are well described by a theory using quantum-kinetic bare Coulomb collisions in the framework of the semiconductor Bloch equations.
