Dataset of Side-Hole Loss Measurements and Spectral Evolution During Evacuation in Anti-Resonant Hollow-Core Fiber

Each spectral data file records 6 sets of spectra with a wavelength range of 400-1200 nm. TRACE A is the unperforated transmission spectrum, while TRACE B to TRACE F correspond to the transmission spectra after drilling 1 to 5 through holes, respectively. The unperforated optical fiber vacuum section was subjected to femtosecond laser (1030 nm, 150 kHz, 8 μ J, approximately 457 fs) incident on a 20 m long AR-HCF, and the emission spectra during the vacuum extraction process at both ends of the fiber were recorded.

The spectrometer uses ideaoptics PG2000PRO and ideaoptics NIR17S. There are a total of 242 spectral data files, with file name prefix P2PR for PG2000PRO measurement results, wavelength range 200-1100 nm, and file name prefix N17S for NIR17S measurement results, wavelength range 900-1700 nm. The spectral data files record the measurement time, with a total recorded vacuum extraction time of approximately 600 minutes. The punching fiber vacuum part still uses a 20 m long AR-HCF, and a through-hole facing the capillary gap is machined at 10 m in the middle of the fiber.

A femtosecond laser (1030 nm, 150 kHz, 8 μ J, about 457 fs) is incident on the AR-HCF about 20 m long, and the emission spectrum during the vacuum pumping process at both ends and the middle through-hole of the fiber is recorded. The spectrometer uses ideaoptics PG2000PRO and ideaoptics NIR17S. There are a total of 74 spectral data files, with file name prefix P2PR for PG2000PRO measurement results, wavelength range 200-1100 nm, and file name prefix N17S for NIR17S measurement results, wavelength range 900-1700 nm.

The spectral data files record the measurement time, with a total recorded vacuum extraction time of approximately 180 minutes.
