Abstract :
Summary form only given. Polishing of glass or diamond is known. A new application of glass surface treatment is presented here. Fine polishing of optical fiber end (silica type), core/cladding surface is performed. A small power monomode longitudinal 10 W continuous wave CO/sub 2/ laser is used. Laser power density is 140 W/cm/sup 2/. The beam is spatially filtered in order to increase the beam uniformity. A decrease of the roughness from 3 microns to less than one hundred of nanometers has been achieved.
