Delivery of nearly diffraction limited picosecond laser pulses in the air-filled anti-resonant hollow core fiber at 1 μm wavelength

This data set contains experimental data and theoretical simulation data of high-energy picosecond laser pulses transmitted in a 5-meter anti-resonant hollow-core fiber:When the laser pulse is transmitted in the air-filled anti-resonant hollow-core fiber, output power and coupling efficiency as a function of input power, powers of the residual incident and stimulated Raman scattering as a function of input power, and the output spectrum under different incident powers.When the laser pulse is transmitted in the vacuumed anti-resonant hollow-core fiber, output power and coupling efficiency as a function of input power, the comparison of the output power of air-filled anti-resonant hollow-core fiber and vacuumed anti-resonant hollow-core fiber at different input powers, and the output spectrum at different incident powers.The output beam quality of laser source, air-filled anti-resonant hollow-core fiber and vacuumed anti-resonant hollow-core fiber at different powers, and the evolution of pulses in spectral domain and time domain.The SEM image of the anti-resonant hollow-core fiber is reconstructed in COMSOL to simulate its dispersion relationship, and then the evolution of the laser pulse in the air-filled anti-resonant hollow-core fiber is reproduced in the spectral domain and time domain.
