Dataset for "Single-mode solarization-free hollow-core fiber for ultraviolet pulse delivery"
The dataset includes all raw data and files to regenerate all figures in the paper, where we report novel anti-resonant silica hollow-core fibers (AR-HCFs) for solarization-free ultraviolet (UV) pulse transmission. We present a single fiber that guides over a part of the UV-C and the whole of the UV-A spectral regions and a second AR-HCF used for delivery of 17 nanosecond laser pulses at 266 nm at 30 kHz repetition rate. By direct comparison we demonstrate that the single-mode AR-HCF significantly outperforms commercially-available high-OH and solarization-resistant silica multimode fibers for pulsed light delivery in this spectral range. MATLAB scripts are also found which filter the straylight background in the raw data measured by UV spectrometer and generate the all attenuation curves in the paper.

Data collection method:
In the cutback measurement, the fiber is rewound in loops in 1 m diameter. Ando AQ6315A and Ocean spectrometer USB4000 are used to measure the transmitted power before and after cut at visible and UV wavelengths respectively. The measurement of 266 nm laser transmitted through hollow-core fiber is by using power meter to directly measure the laser power at the output of fiber. Recording the reading usually takes a few seconds and the average of minimum and maximum power during this period of time is recognized as the transmitted power. The fluorescence is measured by using a short piece of multimode (approx. 15cm) fiber to sample light into Ocean spectrometer.
Data processing and preparation activities:
MATLAB code is to process the raw data measured by Ocean spectrometer. The main purpose of code is to remove the significant background in the spectra due to the straylight. The measured spectral intensities measured before and after cut are input file to be read by MATLAB. Integration time and fiber lengths are needed to generate the corresponding attenuation curves. In the operation, the UV bandedge are required to manually identify on the screen by hand. By clicking the cursor, the X position will be automatically recorded and the local wavelength be recognized as the edge of band. The clicking point should not be at the sharp transitions of band but offset.
