Based on numerical simulations, the authors offer a midinfrared pulse source that uses hollow-core optical fiber filled with gas. Such a source could find applications across a large variety of sectors in science and technology (particularly biomedical), due to its conceptual simplicity. The approach taken in this work resolves all major issues related to pulse generation in the midinfrared spectral region. The system promises to be highly robust against noise, and has a major advantage over existing devices, in using a pump in the 1-μm wavelength range, which is readily available.
