Description: 

The Excel file contains the experimental data that has been used for creating the Figures 1, 2, 4 and 5. 

The figures are as follows:

Figure 1  Reported 790 nm cladding-pumped high power (>50 W) Tm-doped fiber slope efficiencies with respect to launched pump power, as a function of emission wavelength. 

Figure 2  Refractive index profile of the designed and fabricated nested-ring fiber preform, scaled to an 8.2 um diameter core.

Figure 4  TDF power curve with 62 W of 1907 nm from 101 W of launched pump, in addition to the emission spectra at 62 W. 

Figure 5  Beam quality factor (M-squared) analysis of the nested-ring emission profile at 62 W of 1907 nm output.
