Abstract

This dataset is about the data of the plot for tunable 14xx nm thulium doped fiber laser-related performance (output power, optical tunable spectrum, time domain). This dataset contains: [Five xlxs files for the figures in the paper] Figure 3: [Cladding absorption spectrum and QCW pump spectrum]: Measured white-light (“cold”) cladding transmission spectrum in 15 m of TDF (resolution bandwidth (RBW) 0.1 nm) and Combined QCW spectrum of all three 0.79 µm diode lasers at full pump power. Figure 4: [Instantaneous Output power of 1464 nm TDFL and emission spectrum]: Instantaneous TDFL output power vs. launched instantaneous pump power. Blue dots: power at 1.9-μm; red dots: power at 1464 nm; black dots: total output power. (b) 1464 nm output spectrum at full power (RBW: 0.2 nm). Figure 5: [Tunable output spectrum and power at different central wavelength, and also the core propagation loss]: Output power as a function of tuned wavelength and core propagation loss as a function of wavelength. Bottom graph: TDFL output spectra with 0.5-nm RBW at different tuned wavelengths. Gain fiber length 24 m. Figure 6: [length dependence of slope efficiency and output power]: Measured slope efficiency and output power as a function of the length of TDF. Figure 7: [Time domain of Q-switching traces]: Temporal trace of the pulses at maximum 0.79 um pump power;
