Abstract

Mid-Infrared Femtosecond Pulse Generation in Hollow-Core Fibers In article number 2200882, Ang Deng, Wonkeun Chang, and colleagues present a novel approach to generate high-energy femtosecond pulses in mid-infrared from a gas-filled hollow-core fiber. The efficient conversion of near-infrared pump to mid-infrared is facilitated by engineering the cross-sectional geometry of cladding elements in the hollow-core fiber. It promises new opportunities in molecular spectroscopy.
