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%.
