This dataset contains data which are used for generating Fig.1(a)(b)(c)(d), Fig.3(a)(b)(c)(d) and Fig.4(d). These figures are plotted using Origin 2017.

The figures are as follows:

Fig. 1(a)  Evolution of LP08 mode purity in FRA (red curve) and YDFA (black curve) as the LP08-power grows along the fiber against the signal power normalized to the launched pump power.
Fig. 1(b)  Comparison of gain in target HOM (dashed curves) and total signal (solid curves) in FRA (red curves) and YDFA (black curves).
Fig. 1(c)  Normalized transverse intensity profiles of input and output signal of FRA (curves are indistinguishable).
Fig. 1(d)  Normalized transverse intensity profiles of input and output signal of YDFA.
Fig. 3(a)  Measured average-power gain and average pump depletion versus launched peak pump power.
Fig. 3(b)  Pump pulse at input (black curve) and output (red curve) of Raman amplifier at 18 dB signal gain.
Fig. 3(c)  Signal pulse at input (black curve) and output (blue curve) of FRA at 16 dB gain.
Fig. 3(d)  Spectra of amplified signal measured with 0.5 nm resolution for average gain between 0 dB (bottom) and 18.0 dB (top).
Fig. 4(d)  Normalized intensity line profiles (in log scale) for different gain values, 0 dB (black curve), 15.7 dB (red curve), and 18 dB (green curve).
