Definición y significado de F._J._Duarte

From Wikipedia, the free encyclopedia

F. J. Duarte is a laser physicist and author/editor of several well-known books on tunable lasers.^{[1][2][3][4][5][6][7]} He introduced the generalized multiple-prism dispersion theory^[8][9][10] and has discovered various multiple-prism grating oscillator laser configurations.^[11] These configurations include the multiple-prism near-grazing-incidence grating cavities originally disclosed as copper-laser-pumped narrow-linewidth tunable lasers.^[12][13] Duarte's contributions have found applications in a variety of fields including:

• atomic vapor laser isotope separation,^[14][15][16]
• laser medicine,^[17][18][19]
• laser microscopy,^[20][21]
• laser pulse compression,^[22][23][24]
• laser spectroscopy,^[25][26]
• tunable diode lasers.^[27][28]

In the late 1980s, Duarte applied Dirac’s notation to describe quantum mechanically the N-slit interferometer and to solve problems in industrial imaging and optical metrology.^[29][30][31] The electro-optical N-slit interferometer uses beam expansion to illuminate the N-slit array and comprises a photodiode array, at the interference plane, to register the interferograms.^[32] This work also led to a generalized N-slit interferometric equation that was then applied to describe interference, diffraction, refraction, and reflection, in a rational and unified approach.^[33][34]

From the mid 1980s to early 1990s Duarte and scientists from the USArmy Missile Command developed, and demonstrated, ruggedized dispersive narrow-linewidth lasers tunable directly in the visiblespectrum.^[35][36] This work led to experimentation with polymer gain media and in 1994 Duarte reported on the first narrow-linewidth tunable solid-state dye laser oscillators.^[37] These dispersive oscillator architectures were then refined to yield single-longitudinal-mode emission limited only by Heisenberg's uncertainty principle.^[38] His work on solid-state organic-inorganic materials led to the assessment of intra-gain-medium interference phenomena and to the emission of low-divergence homogeneous laser beams from polymer-nanoparticle gain media.^[39] In 2005 Duarte and colleagues were the first to demonstrate coherent emission from an electrically excited organic semiconductor.^{[40] [41]}

He studied physics at Macquarie University (Sydney, Australia) where he also established the successful science reform movement of the late 1970s.^{[42] [43]} Science reform, at Macquarie, was widely supported by local scientists including physicists Ronald Ernest Aitchison, R. E. B. Makinson, and the famed John Clive Ward.^[44] His career path includes post-doctoral research in Australia plus academic, and industrial-research, appointments in the United States.

Tunable lasers for the nuclear energy industry

As previously outlined, Duarte and Piper developed narrow-linewidth multiple-prism grating laser oscillators^[13][45] whose designs have been adopted by various research groups working on atomic vapor laser isotope separation (AVLIS).^[14][15][16] This work^[13][45] was supported by the Australian Atomic Energy Commission.^[45] In 2002 Duarte participated in research that led to the isotope separation of lithium using tunable diode lasers.^[46]
