This dataset contains:

Data used in the generation of figures in the manuscript "Amplification of a radially polarized beam in a thermally guiding ytterbium-doped fiber-rod". 
Data relating to Fig. 7, power of a 1030 nm radially polarized mode as a function of absorbed 915 nm pump light, together with calculated gain, with all errors included.
Data relating to Fig. 2, normalized intensity as a function of sampling angle on an image of a radially polarized mode which has been transmitted through a linear polarizer. For the intention of demonstrating the calculation of the radial polarization extinction ratio, a measure of modal purity.
Data relating to Fig. 4, theoretical modelling of mode radius as a function of distance propagated through the thermally guiding fibner-rod for pump powers of 0 W, 136 W and 1000 W.
The figures are as follows:

Fig. 1. Schematic of the end-pumped 1030 nm radially polarized Yb:YAG laser used as a seed source for the thermally guiding fiber-rod amplifier.
Fig. 2. Example of one of the thirty-six data sets used for calculation of the radial polarization extinction ratio for the seed source.
Fig. 3. Cross-sectional view of the Yb-doped fiber used in TGFR amplifier experiments. 
Fig. 4. Calculated radially polarized beam radius with respect to propagation distance in the thermally guiding fiber-rod. 
Fig. 5. Schematic of the thermally guiding fiber-rod amplifier experiment. 
Fig. 6. Intensity profiles.
Fig. 7. Measured gain for thermally guiding fiber-rod amplifier as a function of absorbed pump power.
