We measured the absorption and photoresponse saturation of GaAs/AIGaAs quantum wells as a function of the incident power. We used picosecond micropulses with a power density up to \(10 \mathrm{GW} / \mathrm{cm}^{2}\) delivered by a free electron laser. First, we compared the absorption in a sample w
