Development of cutting-edge solid-state THz lasers

Terahertz (THz) radiation has the potential to revolutionise the fields of security, medicine and numerous industries, through its application in imaging and spectroscopy. While the applications potential for this technology are immense, there is a significant lack of cost-effective and compact THz radiation sources. At Macquarie University, we are developing frequency-tunable solid-state THz lasers based on stimulated polariton scattering.

This project aims to develop new, compact, high-efficiency and frequency-tunable THz laser sources by making use of stimulated polariton scattering, a process which uses both second-order and third order non-linearities in bulk crystalline materials. This project will involve exploring (through computational modelling and physically constructing) new laser resonator designs which will increase overall THz output power, extraction efficiency and frequency tuning range. Here, the candidate will gain significant experience in the design, construction and characterisation of solid state laser systems; gaining experience in both fundamental laser physics and laser engineering. Engagement with industry partners and end-users of the technology will be a valuable feature of the project.

In addition to scholarly outputs (journal papers and conference presentations), it is anticipated that there will be strong potential for commercialisation of research outcomes and generation of intellectual property, which may be commercialised by our industry partners.

This project is suited to a motivated student who has a strong background in optical physics, with good understanding of non-linear optics and laser system design and operation.
