- Gas-based nonlinear optics in hollow-core fibres: ultrafast dynamics & applications Video: https://tugraz.webex.com/tugraz/j.php?MTID=me6a77c77bcae8cc0a3f302a7e8540e64 Soliton dynamics in gas-filled hollow-core waveguides have brought together nonlinear fibre optics and high field laser science providing new powerful tools for manipulating ultrashort light pulses and an access door to novel nonlinear dynamics. The broadband transmission, the weakly anomalous dispersion and the high-damage threshold of hollow-core fibres grant excellent control over the interplay between linear and nonlinear effects. This allows for the harnessing of pulse propagation dynamics to realise novel light sources with up to PHz bandwidths and in spectral regions otherwise not easily accessible. Furthermore, the high efficiency and the low-pulse energy requirements of these processes facilitate the scaling of these sources to unprecedently high repetition rates. |
