Differential-pressured argon-filled negative curvature hollow-core fiber (NC-HCF) with an anomalous dispersion in the mid-infrared was studied for pulse compression. Preliminary simulation results show compression of 2-micron, 1.8-ps, 50 μJ pulse to 110 fs by using a negative-pressure-gradient argon...
