| Abstract: | Using the phase plate calculated and designed by two-discrete FFT with dimeasionless parameters and computer simulation, the fundamental mode Gaussian beam can be converted in to rectangular shape and the elliptical wavefront can change oint circular symmetrical shape. The relation between theoretical simulation and experimental parameters were derived. Results of simulation show that the experimental equipment is simple by using the data obtained in our method and efficiency of energy transform is high. |
