Abstract
A method for polishing glass, ceramic, and glass-ceramic surfaces. The method includes exposing the surface to ultraviolet laser radiation under conditions effective to smooth the surface. Methods for polishing glass-ceramic surfaces containing spinel crystals using 193-351 nm radiation of a rare gas halide excimer laser operating at about 150 to about 400 mJ/cm.sup.2 are disclosed. Using the methods of the present invention, surfaces having an R.sub.a of about 4 to about 2 .ANG. are produced.
