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.

Summary
Direct write - microphotonics fabrication facility. Direct write-microfabrication, where an ultrafast laser is focussed to a small, intense spot and translated under computer control with respect to a target sample, has emerged as a significant enabling technology creating new opportunities in microphotonics. The proposed facility will enable researchers to modify the internal properties of glass blocks and write 'optical wires' (or waveguides). By combining waveguides with other laser written f ....Direct write - microphotonics fabrication facility.

The proposed facility will enable researchers to modify the internal properties of glass blocks and write 'optical wires' (or waveguides). By combining waveguides with other laser written functional components researchers will develop devices capable of processing optical information. Outcomes will include demonstrations of compact lasers and slow light generation.Read moreRead less
Technologies for space-based optical interferometry. Gravitational waves are ripples in the curvature of space-time produced by the motion of massive celestial objects. Gravitational waves provide a different kind of information about the universe and their measurement will lead to an entirely new type of astronomy. The quest to detect gravitational waves is entering a new era with the Laser Interferometer Space Antenna (LISA) now under development.

Gravitational waves provide a different kind of information about the universe and their measurement will lead to an entirely new type of astronomy. The quest to detect gravitational waves is entering a new era with the Laser Interferometer Space Antenna (LISA) now under development. LISA is a two billion dollar joint NASA/ESA deep space mission to build a gravitational wave observatory in space. This research will develop Australian technologies critical to the success of LISA and other future deep space missions.Read moreRead less

Asymmetric InP-based structures for high power laser diodes at 1400-1500 nm for pumping optical amplifiers used in communication systems. This project is aimed at obtaining high power, single mode 1400-1500 nm wavelength laser diodes using a novel design of asymmetric InP-based structures. These devices are in great demand for pumping of erbium-doped and Raman amplifiers for powering the next generation of dense wavelength division multiplexing optical networks.

This project is aimed at obtaining high power, single mode 1400-1500 nm wavelength laser diodes using a novel design of asymmetric InP-based structures. These devices are in great demand for pumping of erbium-doped and Raman amplifiers for powering the next generation of dense wavelength division multiplexing optical networks. The low modal gain (confinement factor) of this asymmetric structure is expected to reduce internal losses and hence increase the output power with better thermal dissipation. Single mode could be obtained by careful design in the trade-off between filamentation and threshold current. Ion implantation is also proposed to suppress higher order modes.Read moreRead less
