40 mm for WFS20; 11. Within this approximation, a Gaussian beam propagating in free space remains Gaussian, except that of course its parameters evolve. Gaussian beams are usually considered in situations where the beam divergence is relatively small, so that the so-called paraxial approximation can be applied.
