Impact of a micromirror’s shape on GB reflection. (a) A flat mirror on which no focusing effect occurs on the reflected beam; (b) a cylindrical mirror on which the reflected beam can be focused in the tangential plane only; (c) a 3D spherical mirror on which full 3D focusing of the reflected beam can be achieved. 3D, three-dimensional; GB, Gaussian beam.
