Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the fi ....Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the final finish is achieved. We will research this technique for application to unique Australian heritage materials that are important to the specific conservation needs of the Australian War Memorial, the RAAF, Navy and Army Museums, Artlab Australia, and the Art Gallery of NSW.Read moreRead less

Summary
Controlling light to understand and drive nanoscale processes. This project aims to develop a suite of light-based sensing technologies capable of quantifying the dynamic environment within a living cell. These technologies will extend our capacity to harness light-matter interactions at the nanoscale, providing new insights in fields ranging from plant biology to medicine.
Rogue waves in oceans and optical fibres. Rogue waves can sink large ships in the ocean. They appear more commonly than previously thought. Optical rogue waves, the laboratory counterparts of extreme ocean waves, will allow the project to study the main features of the phenomenon, provide the theoretical explanation for their existence and potentially help to eliminate these catastrophic events.
Optically induced spin polarisation: the role of electron-vibration interactions. A defect in diamond has applications as a microscopic probe of magnetic fields, as a fluorescence probe of biological systems and for quantum information processing. These capabilities are to be enhanced by a thorough investigation of the intrinsic properties of the defect centre.

Summary
Optical profiler with dynamic micro electro-mechanical systems capability. This facility will allow Australian researchers to access the world's best capability in dynamic, time resolved, optical three-dimensional profiling of surfaces and devices. It will advance a raft of science research and industry applications characterising natural and artificial materials and underpinning next generation optical, photonic and microelectronic devices.
Exploding solitons. This project builds on previous work in which the existence of exploding solitons was confirmed. Explosions occur regularly in a variety of systems with continuous supply and dissipation of energy. Exploding solitons are more common than ordinary dissipative solitons and occupy large areas in the parameter space. They can be generated relatively easily, however the phenomenon is highly complex. This project aims to further understand exploding solitons so that the phenomeno ....Exploding solitons. This project builds on previous work in which the existence of exploding solitons was confirmed. Explosions occur regularly in a variety of systems with continuous supply and dissipation of energy. Exploding solitons are more common than ordinary dissipative solitons and occupy large areas in the parameter space. They can be generated relatively easily, however the phenomenon is highly complex. This project aims to further understand exploding solitons so that the phenomenon can be used for the generation of pulses with wide spectral output similar to `supercontinuum’ radiation. Research in this direction will provide the basis for building powerful laser sources with wide spectral output.Read moreRead less
Putting stimulated Brillouin scattering to work: tailored optical-phononic interactions for on-chip signal processing. Light interacts with sound via a phenomenon called Brillouin scattering, an effect which is of major importance in modern nonlinear optics but is very difficult to control. Our pioneering project will open the door to low power optical devices and other diverse innovations that will support Australia's needs in defence and communications.
