Femtosecond Pulse Compression via Self-Phase Modulation in 1-Decanol
… of intense pulses focused into gas-filled hollow-core fibres. More recently, multiple crystal plates have been used to broaden the spectrum while using a self-focusing relay to maintain the beam quality. In this thesis, I research substituting solids and gases with liquid alcohols. By using …

Development of hollow-core photonic bandgap fibres free of surface modes
Conventional optical fibres can only guide light in a high refractive index core by total internal reflection. By using total internal reflections it is not possible to guide light in an air core. Light guidance in air is of great interest for various technological and scientific applications and …

Operando fibre Raman sensors for Li-ion battery chemistry
… sensors non-trivial. Combining optical fibres and spectroscopy provides a chemically sensitive sensor that can be embedded directly into the battery with minimal disturbance to the cell operation. This thesis aims to develop and characterise an operando fibre-optic Raman probe, enhanced …
