F. J. Duarte is a Chilean-born laser physicist, inventor, and book author. He has been based in the United States since 1983.
He graduated with First Class Honours in physics from Macquarie University (Sydney, Australia) where he was a student of the quantum and particle physicist J. C. Ward. At Macquarie he also completed his PhD research, on optically-pumped molecular lasers, in 1981. He then became a Postdoctoral Fellow at the University of New South Wales, where he built UV tunable lasers for high-resolution IR-UV double-resonance spectroscopy. Duarte has worked and contributed professionally in the academic, industrial, and defense sectors and has practiced physics in Australia, the Americas, and Europe. He is the author of numerous refereed papers and US patents in the fields of lasers and optics.
Duarte is editor/author of 15 scholarly books including Dye Laser Principles, High-Power Dye Lasers, Tunable Laser Applications, and Tunable Lasers Handbook. He is co-author of Quantum Entanglement Engineering and Applications and sole author of Tunable Laser Optics, Quantum Optics for Engineers, and Fundamentals of Quantum Entanglement. Duarte has made original contributions in the fields of coherent imaging, directed energy, high-power tunable lasers, laser metrology, liquid and solid-state organic gain media, narrow-linewidth tunable laser oscillators, N-slit quantum interferometry, organic semiconductor coherent emission, quantum entanglement, and space-to-space interferometric communications. He is also the author of the generalized multiple-prism grating dispersion theory and has pioneered the use of Dirac’s quantum notation in interferometry and classical optics.
His contributions have found applications in astrometry, cytology, femtosecond laser microscopy, geodesics, gravitational lensing, imaging, laser isotope separation, laser medicine, laser pulse compression, laser spectroscopy, nanobiophotonics, nonlinear optics, polarization rotation, and tunable diode laser design. Current interests include semiconductor organic lasers, tunable laser physics, interferometric theory via Dirac’s notation, and the foundations of quantum entanglement. Duarte was elected Fellow of the Australian Institute of Physics in 1987. In 1981 he joined the OSA, following publication of one of his papers in Applied Optics, and was elected Fellow in 1993. He has received the 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 Optica.
