A fiber-based approach that generates mid-infrared femtosecond pulses in the 3–4 (Formula presented.) m spectral region with microjoule-level single pulse energy is demonstrated. This is realized in a piece of gas-filled antiresonant hollow-core fiber that is pumped by a two-micron light source. A r...
