Fig. 4: Fully characterized VUV pulses tuned between 160 and 190 nm (marked A to D).
From: Temporal characterization of tunable few-cycle vacuum ultraviolet pulses
a, The spectra measured by a VUV spectrometer. b, The average temporal envelopes (solid) and phases (dotted) retrieved from ten independent retrievals of the measured eFROG traces. The shaded areas surrounding the envelopes and phases correspond to the s.d. of the retrievals. The transform limited (TL) pulse shapes corresponding to the measured spectra are displayed as shaded backgrounds. The full-width at half-maximum values of each shape are also included. The VUV pulse energies measured behind the Brewster-angled silicon plates are indicated in the upper left corner of each panel.
