Novel source of excited metastable atoms for Atom Trap Trace Analysis. This project aims to understand and to control light-induced processes in atoms by using finely shaped and tailored laser pulses, focusing on efficient production of excited metastable atoms. This is critical for efficient Atom Trap Trace Analysis, the most advanced technique for dating ground water and geological samples. Expected outcomes of this project include new and enhanced knowledge of physics of light-matter interact ....Novel source of excited metastable atoms for Atom Trap Trace Analysis. This project aims to understand and to control light-induced processes in atoms by using finely shaped and tailored laser pulses, focusing on efficient production of excited metastable atoms. This is critical for efficient Atom Trap Trace Analysis, the most advanced technique for dating ground water and geological samples. Expected outcomes of this project include new and enhanced knowledge of physics of light-matter interactions, developing an efficient, clean source of excited metastable atoms, and integrating that source into the Australian National Facility for dating geological samples. This should provide significant benefits, such as significant improvement of operational efficiency and productivity of that facility.Read moreRead less
Paradigm Shift in Mid-IR Fibre Laser. This project introduces a paradigm shift in 3.5µm mid-IR fibre lasers. A new laser process will be investigated to obtain high-power, simple and robust mid-IR fibre laser design. 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 car ....Paradigm Shift in Mid-IR Fibre Laser. This project introduces a paradigm shift in 3.5µm mid-IR fibre lasers. A new laser process will be investigated to obtain high-power, simple and robust mid-IR fibre laser design. 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
