....can also be carried out using gaussian mode expansions [87] but both of these methods are computationally intensive and sensitive to round o# errors. From another viewpoint, Huygens s integral in scalar form is a convolution integral which can be evaluated using Fourier transform methods [88, 89]. The required Fourier transforms for a uniformly sampled beam profile can then be converted to discrete Fourier transforms, which can be evaluated using the Fast Fourier Transform (FFT) algorithm. The merits of this FFT approach include not only IEEE JOURNAL OF SPECIAL TOPICS IN QUANTUM ....
