Schematic diagram of the autocorrelation setup for simultaneous acquisition of linear and nonlinear interferometric autocorrelation. LPF: longpass filter, SPF: shortpass filter, NLC: nonlinear crystal for SHG, BS: beam splitter, RM: roof mirror, OAP: off axis parabola, FM: flat mirror, W: KRS-5 window, DET0: detector for FEL power monitoring, DET1: detector for acquiring LA traces, and DET2: detector for acquiring nonlinear FRAC traces.
