Laser-based spectroscopic sensing of gas-phase molecules
in agricultural, combustion and environmental media
Professor Brian Orr
MQ Photonics Research Centre, Department of Physics and Astronomy,
Macquarie University, Sydney NSW 2109, Australia
Abstract Laser-spectroscopic techniques for sensing of gas-phase molecules at trace levels in air include those using tunable pulsed optical parametric oscillators (OPOs, both single- and multi-wavelength) and cavity-ringdown spectroscopy (CRDS). The talk will focus on developinginjection-seeded optical parametric oscillators and fiber-coupled CRDS for applications in agricultural, combustion and environmental media. |

Biographical information
Emeritus Professor Brian Orr was educated at the Universities of Sydney (Australia) and Bristol (UK). After a postdoctoral period at the National Research Council of Canada in Ottawa, he returned to Sydney and spent 18 years on the academic staff of University of NSW. At the end of 1987, he became Professor of Chemistry at Macquarie University (also in Sydney, Australia) and then (15 years later) he joined the Department of Physics (and Astronomy) where he has been active for almost 13 years in research, journal editing and cooperative ventures (e.g., setting up the MQ Photonics Research Centre). He is a Fellow of the Optical Society of America (OSA), the Australian Institute of Physics, and the Royal Australian Chemical Institute (RACI). His academic distinctions include the inaugural RACI Physical Chemistry Division Medal (1994), the OpticalSocietyofAmerica’sWilliamF.MeggersAward ‘for outstanding work in spectroscopy’ (2004), and the Australian Optical Society W.H. (Beattie) Steel Medal (2005). He is visiting China to attend the OSA Light, Energy and the Environment Congress (Suzhou, 2–5 November 2015), where he will present an invited talk (with the same title as this seminar – but with different content!)
