From: Deep-UV to Mid-IR Supercontinuum Generation driven by Mid-IR Ultrashort Pulses in a Gas-filled Hollow-core Fiber

Figure 2

Numerically simulated (a) propagation constant mismatch (Δβ) between the soliton and dispersive waves, (b) normalized PSD at z = 0 and z = 30 cm, (c) spectral evolution (normalized to the peak intensity), (d) temporal evolution in dB scale, and (e) intensity at the maximum compression point at z = 7.1 cm for a ~44 μm core HC-AR fiber under 30 bar of Ar gas, pulse energy 8 μJ, pulse duration 100 fs, and pumping in the anomalous dispersion regime at 2460 nm. N: normal dispersion regime, and A: anomalous dispersion regime. The fiber dispersion was calculated using finite-element modeling.
