Ringed photonic crystal fibres for broadband nonlinear optics. The technology developed from this project will enable organic molecules to be detected, identified and quantified. Because the technology is compact, easily engineered and low cost, it will lead to a dramatically increased capability for infrared spectroscopic measurement throughout biology and medicine, with specific benefits in agriculture, the food industry and defence.
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

We will use advanced spectroscopy to characterize the fibre laser dynamics, computer modelling to optimize the laser design, and demonstrate the concept experimentally. The new design will enable agile, high precision polymer processing tailored to the unique absorption lines of carbon-hydrogen bonds in different polymers where there is currently a lack of high power, high brightness low-cost light sources. It will also open the door for very high-resolution laser assisted glass 3D-printing. The project will give Australia a new edge in advanced manufacturing.Read moreRead less

The exhaled breath is a rich source of information about the inner life of the human body - but untangling this complicated molecular mixture into a quantitative measurement of its constituent components is currently an unsolved problem. This project aims to develop a new instrument that leverages the Nobel Prize winning technology of the optical frequency comb to enable analysis of such mixtures. It is expected that by combining a frequency comb source, with an innovative detector and a highly sensitive sampling system, a real-time spectral signature of each sample will be generated. Computational techniques developed by the radio astronomy community will then be used to extract concentrations of individual molecular components at the parts-per-billion level.Read moreRead less
