“…For the case in which ten holes are strongly (1) Let us envision the different diffractional orders illuminated, the relative errors in the 0-1 interval, using as being comprised of individual beams nominally interference terms corresponding to (0,1), (-1,0), and propagating away from the grating at angles given by (1,2), the relative errors are reduced at all points to mX/d for the mth order, X being the optical wavelength, within 0.3%. Because the centers of curvature of the individual beams lie on lines connecting each diffractional beam V. Fraunhofer Diffraction of Gaussian Beams with the grating but do not coincide with the grating, the Consider a Gaussian beam traveling in the + direccenters of curvature for the outgoing mth order beams tion with its waist at r = 0, having an intensity proare distinct.…”
