Abstract

We propose a supercontinuum spectral shaping method that uses the characteristics of a hollow core antiresonance fiber to appropriately attenuate the light of the pump wavelength with a high power density in the supercontinuum spectra, making the spectra flat in a certain wavelength range. In our simulation, the power intensity at the pump wavelength of the supercontinuum pumped by 1064 nm was reduced by 17 dB. In our experiment, a 10-cm-long hollow core anti-resonance fiber was used to reduce the intensity of the pump wavelength of the supercontinuum by 9 dB.
