F J Duarte is an award winning laser physicist. He is the author of the generalized multiple-prism-grating dispersion theory, has discovered a series of tunable laser oscillator configurations, pioneered the use of Dirac's quantum notation in N-slit interferometry and classical optics, introduced extremely elongated laser beams for microscopy/nanoscopy, and derived the quantum entanglement probability amplitude from transparent quantum interferometric principles. His physics has been applied to numerous fields including: astronomy, atomic vapor laser isotope separation, cytology, geodesics, gravitational lensing, imaging, laser medicine, laser microscopy, laser pulse compression, laser spectroscopy, mathematical transforms, molecular diffusion, nanophotonics, nonlinear optics, quantum computing, quantum fluctuations, quantum philosophy, and tunable diode lasers. His book titles are held in some five thousand libraries worldwide. Duarte continues to work on the physics of high-power multiple-prism-grating lasers and on the application of Dirac's quantum notation to classical optics. He is also doing research on N-slit laser interferometers and on the foundations of quantum entanglement. Duarte was born in Santiago, Chile, and his research physics career began at Macquarie University (Sydney, Australia), where he graduated with first class honours in physics and was a student of the celebrated quantum physicist J C Ward. In the United States he has worked in the academic, industrial, and defense sectors. In 2000, with Oxford physicist R H Dalitz, he wrote: "Already in 1948, observations... agreed with quantum mechanics, not with local realism."
