Abstract :
A general method is presented for converting implicit split-step finite-difference propagating beam equations to explicit equations. Higher-order difference approximations can be used for greater accuracy with only minor speed penalties. For the same accuracy, the explicit solutions are often faster than the implicit solutions as well as the standard split-step fast Fourier transform method.<>
