Ultrafast Optics & Instrumentation

New techniques for the characterization and application of ultrafast optical pulses

We are continuously developing new ultrafast science and technology. Including

  • Fundamental dynamical studies of ultrafast material response to laser pulses
  • Imagining and testing new ideas in ultrafast nonlinear optics, such as
    • New frequency conversion, pulse compression and mode-locking techniques
    • Investigating novel soliton dynamics, such as their interaction with plasma, Raman-active molecules and strong-field effects
    • Studying new regimes of ultrafast Raman interaction and four-wave mixing in gases
  • Developing new strategies for CEP stabilization
  • Work on high power fiber amplifier systems to pump OPCPAs
  • Designing pulse and spectral characterization devices spanning the soft-Xray to Mid-IR range

For information of some of the characterisation devices and ultrafast optical beam-line technology we have developed, see our facilities section.

Publications

We demonstrate high-energy resonant dispersive-wave emission in the deep ultraviolet (218 to 375 nm) from optical solitons in short (15 …

Optical soliton dynamics can cause the extreme alteration of the temporal and spectral shape of a propagating light pulse. They occur …

Talks

We demonstrate soliton self-compression of 0.3 mJ pulses to 2.7 fs in a 3 m long gas-filled hollow capillary fibre. Scaling to higher …
