Popis: Recently, the temporal evolution of the amplitude and phase of the chaotic output from a self-amplified free-electron laser was determined. In this letter, we characterize the frequency dependence of the amplitude and phase of the output radiation and discuss the relationship between the characteristics of the spiky intensity structures observed in both the time and the frequency domains. The distribution of the rms time–bandwidth products for an ensemble of output pulses is presented. Experimental results are compared with simulation and theory.
