Hello, today I found time to do concentrate on the proposed zero padding.
My Gaussian beam and the lenses have a diameter of approximately 2^16 array elements while the total array has a size of 2^18. The absolute value of the Gaussian beam multiplied by the lenses converges to zero. Out of this reason I assume that zero padding is not the reason for the horizontal lines. I also inreased the amount of zero padding by the factor of 4 but the horizontal lines were still present. Could something like a difference in the calculation precision (complex numbers) be the reason for the difference between Octave and Numpy?
