The type of laser being developed is called a fibre laser and consists of a laser operating within an optical fibre, the innovation approach used was when these lasers were combined with internal mirrors, known as fibre Bragg gratings.
Unparalleled computing power, ultra-sensitive measurement and fundamental insights into the laws of nature are just a few of the capabilities offered by photonic quantum information science.
Professor Michael Withford’s current research explores femtosecond laser modification of transparent materials, and the development of novel 2D and 3D lightwave devices. Outcomes include fibre Bragg gratings, monolithic waveguide lasers, high power fibre lasers, quantum photonics and interferometric chips for astronomy.
Thomas Meaney’s work presents laser written waveguide circuits to manipulate single photons, demonstrating superb quantum interference in 3D structures, and for the first time combining multiple integrated photon sources – moving towards on-demand photon generation.
A systematic way of characterizing the symmetries of light beams has been developed. This project has shown that symmetric light beams can be used to control light-matter interactions at the nano-scale. Particular applications have been developed, both theoretically and experimentally.
Cerium lasers are unique in that they can produce light that can be tuned across a broad range of wavelengths particularly spanning the UVB part of the ultraviolet spectrum.
Yiqing’s PhD research has broken through the current bio-sensing constraints through his invention of a time-resolved approach called “OSAM”, an Orthogonal Scanning Automated Microscopy suitable for rapid detection of single cells.
The Advanced Cytometry Labs @ Macquarie has invented and demonstrated a library of hypersensitive molecular probes—SUPER Dots—able to pinpoint small numbers of abnormal cells in water, blood and urine.
Diamond’s extraordinary properties are already providing us with massive leaps in optical device performance. In partnership with commercial and government organisations, we are working to exploit these advantages to solve real world challenges.
A collaboration between staff and students of MQ University and Prof Earl Owen of the Microsearch Foundation developed solid protein “solders” for joining severed tissues in microsurgery. Laser light is delivered by optical fibre to cure the protein solder and cause it to adhere to the two tissues to be joined.
