We investigate the dynamics of the Faraday rotation angle by means of time‐resolved pump/probe experiments in CdTe/Cd 1— x Mn x Te multiple quantum wells under high excitation conditions. During the first step of the optical excitation, stimulated emission and amplification of the Faraday rotation is observed. Spectrally resolved measurements reveal that large photoinduced rotation changes can be achieved when the frequency is tuned close to the excitonic resonance and saturation sets in.
