Optical supercontinuum generation from high pulse-energy optical sources. The aim of this project is to develop a broadband and high brightness optical fibre source based on optical supercontinuum generation (i.e. low-coherence optical signals with octave or more bandwidth). Unlike similar sources demonstrated recently which rely on expensive bulk femtosecond pump lasers, this source will be pumped by a large pulse-energy optical fibre laser and use stimulated Raman scattering to seed the contin ....Optical supercontinuum generation from high pulse-energy optical sources. The aim of this project is to develop a broadband and high brightness optical fibre source based on optical supercontinuum generation (i.e. low-coherence optical signals with octave or more bandwidth). Unlike similar sources demonstrated recently which rely on expensive bulk femtosecond pump lasers, this source will be pumped by a large pulse-energy optical fibre laser and use stimulated Raman scattering to seed the continuum generation. The primary outcome will be a compact low-cost all-fibre supercontinuum source with a wide range of applications in areas such as optical metrology, optical coherence tomography, and high resolution non-contact position and motion sensing.Read moreRead less

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

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.
