Xg. Deng et al., PURE-PHASE PLATES FOR SUPER-GAUSSIAN FOCAL-PLANE IRRADIANCE PROFILE GENERATIONS OF EXTREMELY HIGH-ORDER, Optics letters, 21(24), 1996, pp. 1963-1965
A set of recursive formulas for diffractive optical plates design is d
escribed. The pure-phase plates simulated by this method homogeneously
concentrate more than 96% of the incident laser energy in the desired
focal-plane region. The intensity focal-plane profile fits a lath-ord
er super-Gaussian function and has a nearly perfect flat top. Its fit
to the required profile measured in the mean square error is 3.576 x 1
0(-3). (C) 1996 Optical Society of America
