摘要：

Bidimensional excitons are excited resonantly by two consecutive picosecond laser pulses of opposed helicities. Fast circular depolarizations (repolarizations) of the luminescence are observed for short (long) delays between the pulses. These effects are interpreted as manifestations of the exciton-exciton exchange interaction. The principle of a new spin relaxation mechanism of excitons which is controlled by this interaction is presented. Copyright (C) 1996 Elsevier Science Ltd
