Blazed diffraction grating
WebA blazed holographic grating is a diffraction grating where the sinusoidal profile has been transformed into a ‘saw tooth’ profile. This saw tooth profile effectively increases the efficiency of the blazed grating over the … Webn δ(x−nd) is the sampling function (Dirac’s comb) of the grating, and UL(x) is the box function of unit height that limits the total length, L, of the grating. For a blazed grating, a(x) is not purely real, since it carries the additional dephasing due to the blaze with respect to the case of a flat grating.
