Brief Career Outline

F. J. Duarte is a laser physicist; he introduced the generalized multiple-prism grating dispersion theory, has made various unique contributions to the physics and architecture of tunable laser oscillators, and has pioneered the use of Dirac's quantum notation in classical optics.

The generalized multiple-prism dispersion theory is applicable to the design of narrow-linewidth tunable laser oscillators as well as to the design of prismatic pulse compressors for ultrashort pulse lasers. His contributions to tunable laser oscillators include the design and construction of original narrow-linewidth multiple-prism grating (MPG) configurations, initially developed for copper-laser pumped dye lasers, which have also been applied to high-power lasers using gaseous and solid-state gain media. His optimized MPG solid-state laser oscillators have been shown to yield low-divergence, single-longitudinal-mode emission, at the limit allowed by Heisenberg’s uncertainty principle.

These contributions have found applications in astronomy, beam propagation, industrial imaging, laser spectroscopy, medical imaging, medicine, microscopy, optical metrology, and the nuclear industry.

Duarte graduated with First Class Honours in physics from Macquarie University (Sydney, Australia) where he was also awarded a Ph.D. in physics for his research on optically-pumped molecular lasers. His career history includes appointments with Macquarie University, The University of New South Wales, The University of Alabama, State University of New York, the former Photographic Research Laboratories, the former Imaging Research Laboratories (Eastman Kodak Company), the US Army Missile Command, and the US Army Space and Missile Defense Command (as a research analyst). He has also held honorary appointments at Macquarie University, The University of New Mexico, and has served on the editorial boards of Applied Optics, Optics & Photonics News, and Optics Letters. In 2006 he founded Interferometric Optics in Western New York, where he directs its R&D efforts. He is also Adjunct Professor at the University of New Mexico.

Currently, his research focuses on very large N-slit interferometers, space-to-space interferometric communications, miniature narrow-linewidth tunable laser oscillators, multiple-prism dispersion theory, and the application of Dirac's quantum notation to interferometry and classical optics. His latest books are Quantum Optics for Engineers, Tunable Laser Optics, Second Edition, and Tunable Laser Applications, Third Edition. Currently, he is working on a new title: Organic Lasers and Organic Photonics due for publication later in 2018.

The work of Duarte and Taylor, on space-to-space interferometric communications, was selected by Laser Focus World as one of the top technology developments in photonics for 2015. Since 2012 several papers on the fundamentals of quantum entanglement have also been published. Resaerch on N slit interferometers is also bieng applied to the development of aviation instrumentation .

Duarte is the author of approximately 150 archival scientific publications. His contributions are mentioned in nearly two hundred scholarly books, including several classics. Since 2017 he has been appointed Editor of the book series Coherent Sources and Applications for IoP Publishing (London).

Dr. Duarte is a Fellow of the Australian Institute of Physics (1987) and a Fellow of the Optical Society of America (1993). He has received the Paul F. Forman Engineering Excellence Award (1995), for the "invention of the N-slit laser interferometer," and the David Richardson Medal (2016), “for seminal contributions to the physics and technology of multiple-prism arrays for narrow-linewidth tunable laser oscillators and laser pulse compression”, from the Optical Society.
