READ ME File For 'DATASET TITLE' Dataset DOI: 10.5258/SOTON/D0336 ReadMe Author: Lin Xu, University of Southampton This dataset supports the publication: Highly efficient frequency doubling and quadrupling of a short-pulsed Thulium fiber laser Contents +++++++++ This dataset contains which are used for generating Fig.2 to Fig.7. These figures are plotted using origin (Graphics Layout Engine). The scripts of origin are also included in the folds for each figures. The figures are as follows: Fig. 2.(a) Signal spectrum measured after the grating-based filter Fig. 2.(b) Spectrum measured after the polarization-sensitive isolator with different power. Fig. 4 Experimental results of frequency doubling. Fig. 5 Frequency doubling results after pump spectrum was narrowed. Fig. 6 Temperature dependence of the 976 nm power (filled circles) and the sinc2 fit (solid curve). Fig. 7 Experimental results of frequency quadrupling.
