The University of South Australia has landed a $1.8 million government contract to develop technology that underpins the next generation of high-powered lasers in Australia, for the defence and manufacturing sectors.
University of South Australia professor of Laser Engineering David Lancaster will lead the three-year project, funded by the Defence Science and Technology Group (DSTG), in collaboration with the University of Adelaide.
Lancaster, who heads one of the country’s leading laser and photonics manufacturing research laboratories at the University of South Australia, will use the funding to help build sovereign manufacturing capability. This will bring Australia up to speed with other developed nations.
“High-powered lasers are increasingly being used in defence and manufacturing, but despite a long history of developing lasers in Australia our technology is still relatively immature compared to other countries,” Lancaster said.
“There is a substantial gap between the research outputs and the needs of our defence industry, so Australia has had to buy this technology from other countries, which is quite restrictive because most nations severely limit their exports of lasers.”
Over the next three years, Lancaster aims to build new high-powered lasers that combine multiple smaller lasers, fine tuning the manufacturing process so it is cheaper and more efficient.
“In the past, I have worked on lasers that take years to build and cost millions of dollars,” Lancaster said.
“I think it’s more important to put years of effort to develop the technology and manufacturing processes, to build many miniature and safer lasers which cost hundreds of dollars each. That is our aim.”
The University of South Australia’s Laser Physics and Photonics Devices Lab will manufacture the lasers and the University of Adelaide’s Institute for Photonics and Advanced Sensors will develop the specialist laser glass.
Australian universities and defence sector need to be more closely integrated to build sovereign independence in laser technology, Lancaster said.
“The reason that UniSA and the University of Adelaide have been selected for this project is that our miniature laser technology and manufacturing processes are world leading, and will supercharge the DSTG’s laser system program,” he said.
High-powered lasers are the preferred tools for the manufacturing sector to cut, shape and weld industrial materials with a high level of precision.
Their ability to manipulate and transform materials makes them ideal for the automotive, computer and clothing industries as they can create extremely fine features that are near impossible to make using traditional machining equipment.
