Split mirror arrangement. (a) A schematic of the experimental set-up of the autocorrelator consisting of a split spherical mirror and a TOF spectrometer. (b) Calculated (left panels) and measured (right panels) transverse intensity distribution of a CW 532 nm laser at the focus of the spherical mirror for Δτ = 0 and Δτ = TL/2 (double maximum distribution) delay. (c) High-order autocorrelation trace of the fundamental laser field (IR) obtained measuring the Ar+ yield as a function of the time delay between the two pulses produced by the split mirror. For this acquisition, the harmonic generation was turned off and the Sn filter was removed. (d) Expanded area of the AC trace. The signal is oscillating at the laser period of 2.67 fs.
