The figures are as follows:

Fig. 2  (a) Measured doping concentration of a representative fabricated Ge/Tm co-doped fiber, (b) the normalized absorption cross-section of the Al/Tm co-doped fiber and our in-house fabricated Ge/Tm co-doped fiber, respectively. 
Fig. 3  (a) Normalized emission cross-sections for Al/Tm co-doped fiber and in-house fabricated Ge/Tm co-doped fiber, respectively, and (b) the calculated normalized gain coefficient of Ge/Tm co-doped fiber at different population inversion levels. 
Fig. 4  (a) Schematic of a short-wavelength TDFA, TLS: tunable laser source, (b) gain and NF performances of the TDFA, and (c) amplified spectra for saturated signals, measured with 0.1 nm OSA resolution.
Fig. 5  (b) output power of the tunable TDFL at different lasing wavelengths, (c) output spectra of the tunable TDFL (measured with 0.1 nm OSA resolution) and (d) slope efficiency at 1660 nm at port 1.
