| Abstract: | A new Fourier itertive optimization algorithm has been proposed to design phase-only diffractive elements for laser beam shaping. By computer simulation, it's found that this algorithm can provide faster convergence speed, more powerful ability to overcome local minimum problem and better shaping quality than GS algorithm and input-output algorithm with the same initial phases provided by the geometrical transformation method. |
