Summary
A Transportable Optical Frequency Counter, Synthesizer and Super-Continuum Generator (OFCSSG). 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.

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
Optical supercontinuum generation from high pulse-energy optical sources. The aim of this project is to develop a broadband and high brightness optical fibre source based on optical supercontinuum generation (i.e. low-coherence optical signals with octave or more bandwidth).

The aim of this project is to develop a broadband and high brightness optical fibre source based on optical supercontinuum generation (i.e. low-coherence optical signals with octave or more bandwidth). Unlike similar sources demonstrated recently which rely on expensive bulk femtosecond pump lasers, this source will be pumped by a large pulse-energy optical fibre laser and use stimulated Raman scattering to seed the continuum generation. The primary outcome will be a compact low-cost all-fibre supercontinuum source with a wide range of applications in areas such as optical metrology, optical coherence tomography, and high resolution non-contact position and motion sensing.Read moreRead less
Ringed photonic crystal fibres for broadband nonlinear optics. The technology developed from this project will enable organic molecules to be detected, identified and quantified. Because the technology is compact, easily engineered and low cost, it will lead to a dramatically increased capability for infrared spectroscopic measurement throughout biology and medicine, with specific benefits in agriculture, the food industry and defence.

Detection and characterisation of micro-organisms such as airborne biological agents, parasites in domestic water supplies and micro-organisms used in the food and beverage industry, is of national importance. All biological systems have rich absorption signatures in the UV enabling detection of biological specimens with high sensitivity and selectivity using optical methods. For these applications compact and inexpensive tunable UV lasers are required; however to date tunable UV lasers have been limited to bulky and expensive systems. We propose to engineer novel, low cost, compact, tunable UV cerium lasers and demonstrate their applicability to selective optical detection of micro-organisms.Read moreRead less
