On-axis spectral intensity is blue-shifted and off-axis spectral intensity is red-shifted with increasing radial coordinate. From our main results, one derive some published particular cases of the considered beam.

NettetTranslations in context of "beam diffracted through" in English-French from Reverso Context: We could have just missed them because they would modify Bragg's diffraction laws (which stipulate that a beam diffracted through a crystal has the same frequency before and after diffraction) in a subtle way. NettetTypically, the intensity that is diffracted into m = 0 order can be varied between 15% to 99% of the input light intensity. Likewise, the intensity of the m = +1 order can be varied between 0% and 80%. An expression … NettetDiffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the … the briggs concrete block
