Clocks and oscillators are crucial for the highest precision scientific and industrial measurements and are the foundation of modern communications technology. Recent developments in laser-cooled optical clocks promise a wave of revolutionary changes to global navigation, timekeeping and precision measurement. Our group has already achieved world's-best performance in this field. To stay at the forefront of this wave we propose a broad-ranging program of research aimed at:
- new clocks of 100 times higher performance than any existing clock,
- development of extremely low noise photonic oscillators,
- the application of these new technologies to test the foundations of Physics, including involvement in a space-based experiment.

Redefining Temperature. The international system of units, which is at the basis of every accurate measurement, requires coherent definitions for its basic units (eg. metre, second, kelvin). Unfortunately, at the moment this is not so, and a global call has gone out to redefine every basic unit in terms of fundamental constants, which are by definition the same anywhere and anytime. This project will develop a new laser-based approach to measuring temperature which can be widely deployed and us ....Redefining Temperature. The international system of units, which is at the basis of every accurate measurement, requires coherent definitions for its basic units (eg. metre, second, kelvin). Unfortunately, at the moment this is not so, and a global call has gone out to redefine every basic unit in terms of fundamental constants, which are by definition the same anywhere and anytime. This project will develop a new laser-based approach to measuring temperature which can be widely deployed and uses fundamental principles for its operation: this can bring accuracy to thermometry in industry for the first time. These outcomes will generate high-level recognition for this Australian project and provide opportunities for high level research training.Read moreRead less

Gravitational waves are expected to offer humanity a completely new spectrum with which to study the Universe. Australia has been a pioneer in the quest to open up this new spectrum. This project will allow Australia to play a key role in a world-wide project which aims for the first time to enable gravitational waves to be detected from black holes and neutron stars throughout the universe. It will give Australia access to developed technologies, and will be a major boost to physical science research and education.Read moreRead less
The Quest for Ultimate Measurement Precision. Precision measurement is the foundation upon which modern technological society is built. The highest quality measurement devices rely on stable clocks for their operation.

Precision measurement is the foundation upon which modern technological society is built. The highest quality measurement devices rely on stable clocks for their operation. The group's existing research has been aimed at developing some of the world's most precise measurement tools based on clocks and lasers. In parallel with this, other scientists have developed the means for exquisite control of light on the microscopic scale. By combining these two technologies, both of which lie at the extreme limit of precision, the group will develop a new generation of technology for fundamental science objectives as well as for industrial needs.Read moreRead less

The generation of ultra-short light pulses of just a few femtoseconds (one thousand-trillionth of a second) in duration has enabled applications in a wide range of fields, but complexity and cost has limited availability. This project will employ recently developed optical fibre and solid-state laser technology to create a cost-effective compact transportable facility of highly coherent, ultra-broadband radiation. The source will enable new research and substantially enrich existing research in optical time standards and metrology, in-vivo biological imaging, and ultrafast spectroscopy. No such facility is presently available in AustraliaRead moreRead less
