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.
