Bragg-Gleichung – Wikipedia
WebTime-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector ( DBR) is a reflector used in waveguides, such as optical fibers. Bragg diffraction (also referred to as the Bragg formulation of X-ray diffraction) was first proposed by Lawrence Bragg and his father, William Henry Bragg, in 1913 in response to their discovery that crystalline solids produced surprising patterns of reflected X-rays (in contrast to that of, say, a liquid). They found … See more In physics and chemistry , Bragg's law, Wulff–Bragg's condition or Laue–Bragg interference, a special case of Laue diffraction, gives the angles for coherent scattering of waves from a crystal lattice. It encompasses the … See more Bragg diffraction occurs when radiation of wavelength λ comparable to atomic spacings, is scattered in a specular fashion (mirror-like reflection) by the atoms of a crystalline system, … See more A colloidal crystal is a highly ordered array of particles that forms over a long range (from a few millimeters to one centimeter in length); colloidal … See more Bragg's law, as stated above, can be used to obtain the lattice spacing of a particular cubic system through the following relation: where $${\displaystyle a}$$ is the lattice spacing of the See more When X-rays are incident on an atom, they make the electronic cloud move, as does any electromagnetic wave. The movement of these charges re-radiates waves with the same frequency, blurred slightly due to a variety of effects; this phenomenon is known as See more Volume Bragg gratings (VBG) or volume holographic gratings (VHG) consist of a volume where there is a periodic change in the refractive index. Depending on the orientation of the … See more • Bragg plane • Crystal lattice • Diffraction • Distributed Bragg reflector • Dynamical theory of diffraction See more WebAs the reflection occurs only in a short wavelength range, the volume Bragg grating can also be used for injecting pump light into a laser resonator: even if pump and laser wavelength are very close together, the grating may reflect laser light and transmit pump light, or vice versa. dewitt church supply
