Abstract:
A set of recursive formulas for diffractive optical plates design is described. 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 12th-order super-Gaussian function and has a nearly perfect f lat top. Its fit to the required profile measured in the mean square error is 3.576 x 10(-3).
