Improving Fibre Laser Sources for Future Gravitational Wave Detectors

Gravitational wave interferometers require ultra-stable lasers to achieve their ultimate sensitivity.

Unfortunately, environmental effects degrade the performance of the laser. In this project you will join the team developing 2 µm fibre laser sources and investigate the isolation of the laser cavities from the environment.

This could include the development of seismic actuation and sensing systems, the design of temperature control and isolation hardware and the investigation of liquid metal cooled fibre lasers.

This project is part of the research program within the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav), and includes research toward upgrading the sensitivity of the current generation of detectors, analysing data from those detectors and the development of technology for future detectors.
