For gravitational-wave detections and analyses, the raw outputs from the gravitational-wave detectors need to be converted into analysable data through some calibration apparatus. This project investigates new techniques to improve calibration accuracy and precision and better integrate the calibration bias into astrophysical analyses. 

Gravitational wave detectors have reached the thermodynamic limit of optical coatings. Further sensitivity improvements require new coating materials and noise mitigation techniques. This project models the behaviour of higher order spatial laser modes in optical resonators for measuring coating thermal noise directly.

Gravitational wave detectors have reached the thermodynamic limit of optical coating performance and require novel coating materials and noise mitigation techniques for further sensitivity improvements. This project is to implement a phase tracking system for the optical beat between two 2µm-band lasers for coating thermal noise measurements.

Gravitational wave detectors have reached the thermodynamic limit of optical coating performance and require novel coating materials and coating noise suppression techniques for further sensitivity improvements. This project is to design a high-bandwidth feedback control system to stabilise the intensity and frequency of a 2µm-band laser for investigations of thermal noise in experimental mirror coatings.
