Abstract

This dataset is about the data of the plot for Q-switching 821 nm laser-related performance (output power, pulse energy, spectrum, time domain). This dataset contains: [Three xlxs files for the figures in the paper] Figure 3: [Cladding absorption spectrum and side fluorescence spectrum of gain fiber]: Measured white-light (“cold”) cladding transmission spectrum in 15 m of TDF (resolution bandwidth (RBW) 0.1 nm) and side fluorescence spectrum from 750 nm to 900 nm under 60 W pumping (RBW 2 nm). Figure 4: [Output power and pulse energy performance, also the optical spectrum]: Pulse energy (including inter-pulse energy) and average power versus repetition rate in Q-switched regime of operation; Optical spectrum of the Q-switched TDFL at maximum repetition rate (resolution bandwidth 1 nm). A filter suppressed wavelengths shorter than ~797 nm. Figure 5: [Time domain of Q-switching traces]: Temporal trace of the pulse train at maximum repetition rate of 1.025 kHz; (b) single pulse at maximum repetition rate and pump power with higher bandwidth.
