The nontrivial features of phase fluctuations in optical phase-conjugating mirror had been studied via Michelson interferometer with two independent PC-mirrors . The phase-conjugating Michelson interferometry is a promising technology for coherent summation of laser amplifiers . See more The Michelson interferometer is a common configuration for optical interferometry and was invented by the 19/20th-century American physicist Albert Abraham Michelson. Using a beam splitter, a See more White light has a tiny coherence length and is difficult to use in a Michelson (or Mach–Zehnder) interferometer. Even a narrowband (or "quasi-monochromatic") spectral source requires careful attention to issues of chromatic dispersion when used to illuminate … See more Step-phase interferometer This is a Michelson interferometer in which the mirror in one arm is replaced with a Gires–Tournois etalon. The highly dispersed wave reflected by the Gires–Tournois etalon interferes with the original wave as … See more A Michelson interferometer consists minimally of mirrors M1 & M2 and a beam splitter M. In Fig 2, a source S emits light that hits the beam splitter (in this case, a plate beamsplitter) surface M at point C. M is partially reflective, so part of the light is transmitted … See more The Michelson interferometer configuration is used in a number of different applications. Fourier transform spectrometer Fig. 5 illustrates the operation of a Fourier transform spectrometer, which is essentially a … See more • List of types of interferometers • LIGO Laser Interferometer Gravitational-Wave Observatory • NPOI See more • Diagrams of Michelson interferometers • Application of a step-phase interferometer in optical communication See more WebOct 28, 2014 · We present a method of noise suppression of laser diodes by an unbalanced Michelson fiber interferometer.
