Abstract
We investigate the dynamics of the Faraday rotation angle by means of time-resolved pump/probe experiments in CdTe/Cd1-xMnxTe multiple quant um wells under high excitation conditions. During the first step of th e optical excitation, stimulated emission and amplification of the Far aday rotation is observed. Spectrally reserved measurements reveal tha t large photoinduced rotation changes can be achieved when the frequen cy is tuned close to the excitonic resonance and saturation sets in.
