Stabilisation of transverse mode purity in a radially polarised Ho:YAG laser using machine learning

Dataset for the article 'Stabilisation of transverse mode purity in a radially polarised Ho:YAG laser using machine learning' in Applied Physics B. This dataset contains the data used in the generation of Figures 3, 6 and 8 in the manuscript. The figures are as follows: Fig. 3. Beam propagation factor (M2) of the radially polarised Ho:YAG laser at 28 W of incident pump power, indicating a high quality LG01 mode. Inset: emission spectrum. Fig. 6. Variation of the radial polarisation purity as a function of incident pump power when the machine learning stabilisation is, or is not, being used. Fig. 8. Output power curves for the Ho:YAG laser with either no machine learning stabilisation, radial LG01 stabilisation or fundamental HG00 stabilisation.
