Data for Reducing Nonlinear Limitations of Ytterbium Mode-Locked Fibre Lasers with Hollow-Core Negative Curvature Fibre

The data behind the four figures shown in the paper. Including example autocorrelation traces and pulse spectra for figure 2. The latter 2 datasets summarize the peak power results and single pulsed modelocking ranges for the laser cavities built as shown in figure 3.
