Adaptive optics is a technique for correcting wavefront distortions in light beams to improve optical imaging performance. The Research Network for Adaptive Optics aims to draw together isolated Australian and New Zealand research groups working on adaptive optics applications in disparate areas to achieve a critical mass of researchers in this burgeoning field. Adaptive optics has wide application in areas as diverse as astronomy, vision science, ophthalmology, microscopy, optical communications, laser radar, and laser beam shaping. The Research Network will coordinate and expand Australian involvement in these areas and inform industry, as have similar networks in the USA and Europe.Read moreRead less
Scaling-up microstructured fibres for terahertz radiation. Terahertz radiation is the last region of the electromagnetic spectrum to be fully utilised. Many applications have been identified but their practicality has been limited by a lack of low-loss flexible waveguides. The waveguides to be developed in this project will build on Australia's existing international lead and investments in photonics as well as extend the dynamic field of microstructured optical fibres, indentified as the 'futur ....Scaling-up microstructured fibres for terahertz radiation. Terahertz radiation is the last region of the electromagnetic spectrum to be fully utilised. Many applications have been identified but their practicality has been limited by a lack of low-loss flexible waveguides. The waveguides to be developed in this project will build on Australia's existing international lead and investments in photonics as well as extend the dynamic field of microstructured optical fibres, indentified as the 'future' of optical fibres. Low-loss flexible waveguides will enable imaging and spectroscopy applications that can reveal and object's internal structure and composition. This will have immediate applications in security, quality control, medical imaging and other safety or industrial applications.Read moreRead less

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).

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

We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing. A new generation of Raman crystals, especially tungstates, offer superior optical, mechanical and thermal properties, promising high Raman gains and choice of Stokes frequency shift. The project will investigate a range of key issues for these materials including control of the Stokes wavelength, associated polarisation control, and pump-resonator configurations giving maximum Raman laser power and efficiency. The project will lead to state-of-the-art source technology with outstanding prospects for commercialisation and practical application.Read moreRead less
