From: Full characterization of superradiant pulses generated from a free-electron laser oscillator
(a) FEL spectrum deduced by Fourier transformation of the LA trace and retrieved relative spectral phase. (b) Measured and retrieved FRAC traces. (c) Retrieved pulse structure and relative phase. (d) Retrieved pulse structure and relative phase after subtraction of the dispersion effect of the refractive optical components in the beam path.
