Francisco Javier "Frank" Duarte is a laser physicist and author/editor of several books on tunable lasers and quantum optics. His research on physical optics, quantum optics, and laser development has won several awards. He has made numerous original contributions to tunable lasers, multiple-prism optics, quantum interferometry, and quantum entanglement. Dr. Duarte was elected Fellow of the Australian Institute of Physics in 1987 and Fellow of the Optical Society (Optica) 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 his seminal contributions to the physics of narrow-linewidth tunable lasers and the theory of multiple-prism arrays for linewidth narrowing and laser pulse compression.
