RICHARDSON AND LIN XU TITLE:High-energy, mid-IR, picosecond fiber-feedback optical parametric oscillator JOURNAL: Optics Letters This dataset contains experimental data for the paper: The figures are as follows: Fig. 2 Measured (a) Optical spectra of the MOPA output at different powers (inset shows the signal peak with a higher spectral resolution) and (b) optical pulse of the MOPA output. Fig. 4 Cutback plot of the HCF fiber used in the fiber-feedback OPO cavity Fig. 5 Average idler power, average signal power and conversion efficiency against pump power for a) the solid-core fiber-feedback OPO and b) the HCF fiber-feedback OPO. Fig. 6 Spectra of (a) signal and (b) idler for the solid-core fiber-feedback OPO at maximum and low powers Fig. 7 Spectra of (a) signal and (b) idler for the HCF fiber-feedback OPO Fig. 8 Tunability of the (a) signal and (b) idler from the fiber-feedback OPO and the corresponding maximum power Date of data collection: 08/10/2020 - 28/01/2022 Geographic location of data collection: University of Southampton, U.K. Related projects: Engineering and Physical Sciences Research Council (EPSRC) (AirGuide Photonics Programme Grant (EP/P030181/1), Laser Technologies for Future Manufacturing Platform Grant (EP/P027644/1), InLightenUs Transformative Healthcare 2050 project (EP/T020997/1)), European Research Council (ERC) (Lightpipe, grant agreement no.682724).
