1Resonance-enhanced multi-octave supercontinuum generation in antiresonant hollow-core fibers显示文摘Ultrafast supercontinuum generation in gas-filled waveguides is an enabling technology for many intriguing applications ranging from attosecond metrology towards biophotonics,with the amount of spectral broadening crucially depending on the pulse dispersion of the propagating mode.In this study,we show that structural resonances in a gas-filled antiresonant hollow core optical fiber provide an additional degree of freedom in dispersion engineering,which enables the generation of more than three octaves of broadband light that ranges from deep UV wavelengths to near infrared.Our observation relies on the introduction of a geometric-induced resonance in the spectral vicinity of the ultrafast pump laser,outperforming gas dispersion and yielding a unique dispersion profile independent of core size,which is highly relevant for scaling input powers.Using a krypton-filled fiber,we observe spectral broadening from 200 nm to 1.7μm at an output energy of B 23μJ within a single optical mode across the entire spectral bandwidth.Simulations show that the frequency generation results from an accelerated fission process of solitonlike waveforms in a non-adiabatic dispersion regime associated with the emission of multiple phase-matched Cherenkov radiations on both sides of the resonance.This effect,along with the dispersion tuning and scaling capabilities of the fiber geometry,enables coherent ultra-broadband and high-energy sources,which range from the UV to the mid‐infrared spectral range.Rudrakant Sollapur Daniil Kartashov Michael Zürch Andreas Hoffmann Teodora Grigorova Gregor Sauer Alexander Hartung Anka Schwuchow Joerg Bierlich Jens Kobelke Mario Chemnitz Markus A Schmidt Christian Spielmann 2017Light(Science & Applications)2017,6,1:2
