Brian J. Orr is an Australian scientist known for various experimental and theoretical contributions to molecular and optical physics, including laser spectroscopy and optical parametric oscillators.
He received his PhD from the University of Bristol (UK) in 1968 and, after a postdoctoral period in Ottawa (Canada), returned to Sydney in 1969 to take up an academic position at the University of New South Wales.
[1] Since 2003, Orr has been an Emeritus Professor, based in Macquarie University’s Department of Physics and Astronomy.
Orr has been an editor for the international journals Optics Express, JOSAB and Chemical Physics Letters.
[citation needed] Many of the accomplishments of Brian Orr and his research students and colleagues have been summarized in the Optical Society's citation for his 2004 W. F. Meggers Award: "for advancing molecular spectroscopy by experiment and theory on infrared- and Raman-ultraviolet double resonance, coherent Raman spectroscopy, cavity ringdown spectroscopy, photoelectron spectroscopy, nonlinear optics, and tunable coherent light sources.
