B. Gaussian Beam Transformation by a Lens.
... An ideal lens does not change the transverse profile of an optical field, so the Gaussian beam will remain a Gaussian at every point in the system. But, the wavefront curvature will be changed, as the beam passes through the lens, resulting in new values of waist position and waist diameter. Since t ...
