Fig. 6: Central-wavelength tuning of the broadband UV DW.
From: Octave-wide broadening of ultraviolet dispersive wave driven by soliton-splitting dynamics
The broadband DW spectra with different emission wavelengths are measured at different Ne-gas pressure from 3 bar to 7 bar. The pump pulse used in the experiment has a temporal width of 18 fs and the HCF has a length of 42 cm and a core diameter of 100 μm. These results are also plotted on the coordinate axis of spectrum versus frequency, see Supplementary Fig. S17.
