Abstract
Optical saturation experiments are widely used to determine the lifeti me T1 of photoexcited states. Unfortunately, such experiments require the simultaneous knowledge of the phase relaxation time T2 and an abso lute calibration of the light intensity I in the sample, rendering the analysis of such experiments hazardous. The present contribution illu strates how this problem can be solved by using free electron lasers l ike FELIX yielding trains of short pulses instead of quasi-cw radiatio n.
