ABSTRACT:
A method for shaping the surface of an optical target, said method comprising the steps of: addressing a ring of laser radiation to the surface of the optical target domain, said laser radiation being of sufficient fluency and energy to photoablate the material forming the body of said optical target domain, sweeping the optically functional portion of said target domain with said laser ring by effectively changing the radius of said ring in a prescribed fashion within the range of the radius of the optical target domain and zero.
