Abstract :
A new procedure is presented for calculating the shape of focusing mirrors by controlling the phase distribution of Gaussian beams. The angle of incidence and three of the four beam parameters (beam waist radii and focal lengths of the incident and reflected beams) can be chosen arbitrarily. The remaining quantity is computed so that the beam radii of both beams are matched to each other at the center of the mirror.<>
