Solitons are self‐sustaining optical pulses that arise from the precise balance of anomalous dispersion and Kerr nonlinearity in a fibre. Their remarkable stability over long distances underpins ...

Three-dimensional schematic and cross-sectional view of a holmium-doped ZBLAN photonic crystal fiber, illustrating the microstructured air-hole cladding, air-hole diameter (dₐ), and pitch (Λ). The ...

Generating intense ultrashort pulses with high spatial quality has opened up possibilities for ultrafast and strong-field science. It is so important that the Nobel Prize in Physics 2018 was given to ...
