WebReflection vs. Transmission Gratings The two broadest categories of diffraction gratings are reflection and transmission gratings. Figures 1 and 2 show reflection gratings, which are essentially mirrors with microscopic grooves. All diffracted orders reflect off of the grating at different angles. 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.

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.
