Quantum information and communication is a new paradigm in information technology which utilises quantum physics to improve current limitations in speed, security and fidelity of information transmission and processing, extending the present Electronics and Photonics devices. Future applications will include teleportation, cryptography and ultimately quantum computation. We propose to investigate these applications using continuous (CW) laser beams and the Einstein-Podolsky-Rosen (EPR) quantum entanglement, which is generated via a pair of optical parametric oscillators. The advantage of CW over the established single photon technology is better detection efficiency, wider data bandwidth and a compatibility with existing photonics technology.Read moreRead less

A Laser Guide Star using a High Power, Synchronously Pumped Optical Parametric Oscillators. We will develop a novel high power source of 589nm coherent (laser) light to be used to create a laser guide star by exciting sodium atoms in the earth's upper atmosphere (the mesosphere). This is needed to determine the distortion caused by the atmosphere on an optical beam propagating through it and generate the information needed to correct those distortions using an adaptive optics telescope.

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.

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
