The behavior of a FEL operating in the pulsed saturated regime, is rep
roduced by the FEL integral equation, suitably modified to include non
-linear effects. The method allows to evaluate the FEL dynamics by mea
ns of a relatively negligible computer time. The relevant predictions
are compared with available experimental and numerical data.
