F. J. Duarte introduced the generalized multiple-prism 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, medical imaging, medicine, microscopy, optical metrology, spectroscopy, and the nuclear industry.
He 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 The University of New South Wales, The University of Alabama, the US Army Missile Command (as an analyst), and the former Photographic Research Laboratories (Eastman Kodak). 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. Currently, he is a research physicist with Interferometric Optics, Western New York, USA.
Dr. Duarte's contributions are cited in more than 100 laser and optics books including several classics. He received the Engineering Excellence Award from the Optical Society of America, is a Fellow of the Australian Institute of Physics, and a Fellow of the Optical Society of America.
