Random laser frequency fluctuations degrade the performance of interferometric metrology systems. This limits the sensitivity in numerous measurements, such as high-resolution displacement and spectrometry, as well as fibre optic sensing of seismic and acoustic signals. Hence, reducing laser frequency noise is of great importance to the field of optical metrology.
This project will work on advanced interferometric techniques, using electro-optics to stabilise a laser to an optical reference to achieve ultra low frequency noise performance. It will study the use of an optical fibre interferometer as a frequency reference and its fundamental noise properties. We will engineer a housing chamber for the optical reference to isolate it from mechanical and thermal noise in the environment.
