Frases de F. J. Duarte

Francisco Javier Duarte es un físico e inventor chileno. Es autor de varios libros sobre láseres de colorante,[1]​[2]​[3]​ láseres sintonizables,[4]​[5]​[6]​[7]​[8]​[9]​ y óptica cuántica.[10]​ Duarte ha hecho importantes contribuciones en el área de osciladores integrados por sistemas prismáticos[11]​[12]​ y también es autor de la teoría de dispersión generalizada en sistemas de prismas múltiples.[13]​

En 1994 Duarte demostró por primera vez la oscilación de banda angosta en un láser de colorante sólido usando uno de sus diseños de osciladores dispersivos.[14]​ Estos osciladores fueron modificados en forma óptima en 1999 demostrando oscilación láser cerca del límite permitido por el principio de incertidumbre de Heisenberg.[15]​ Otra de sus áreas de investigación es la aplicación de la notación de Dirac en interferometría y óptica clásica.[6]​[16]​

Sus trabajos han sido aplicados en numerosos campos de investigación incluyendo: compresión de pulsos láser,[17]​[18]​[19]​ espectroscopia,[20]​[21]​ geodésica, [22]​láseres semiconductores sintonizables,[23]​[24]​ lentes gravitacionales,[25]​ medicina láser,[26]​[27]​[28]​ microscopía láser,[29]​[30]​ óptica no lineal,[31]​ y separación de isótopos por láser.[32]​[33]​[34]​ Wikipedia

“All the indistinguishable photons illuminate the array of N slits, or grating, simultaneously. If only one photon propagates, at any given time, then that individual photon illuminates the whole array of N slits simultaneously.”

“The EPR claim of an "all values" spread in the coordinate depends on an idealized absolute and exact measurement of p with \Delta p\ = 0. Since this is physically impossible, the claim of "no physical reality" can be negated.”

“The Dirac notation, though originally applied to the propagation of single particles, also applies to describing the propagation of ensembles of coherent, or indistinguishable, photons.”

“The two photons are entangled and according to local realism, their polarization planes should become independent… a typical EPR situation. Already in 1948, observations… agreed with quantum mechanics, not with local realism.”

“The longer the cavity and the narrower the beam waist, the better the beam quality of the laser emission, or
|\langle x | s \rangle|^2\ = \sum_{j=1}^\N\, \Psi(r_j)^2\ +2 \sum_{j=1}^\N\, \Psi(r_j)\bigg(\sum_{m=j+1}^\N\, \Psi(r_m)cos(\Omega_m-\Omega_j)\bigg) </math”

“Personally, I find the concept of a "final theory," or a "theory of everything," rather limiting. The fun of discovery will most likely last as long as the human race continues.”

“Feynman uses Dirac's notation to describe the quantum mechanics of stimulated emission… he applies that physics to… dye molecules… In this regard, Feynman could have predicted the existence of the tunable laser.”

“Multiple-prism arrays were first introduced by Newton (1704) in his book Opticks. In that visionary volume Newton reported on arrays of nearly isosceles prisms in additive and compensating configurations to control the propagation path and the dispersion of light. Further, he also illustrated slight beam expansion in a single isosceles prism.”

“Regardless of the prophetic value of Dirac’s description [on interference] his was probably the first discussion… including a coherent beam of light. In other words, Dirac wrote the first chapter in laser optics.”
