A new application of glass surface treatment is presented here. Fine polishing of optical fiber end core/cladding surface, is performed. A small power monomode longitudinal 10 W cw CO2 laser is used. A decrease of the roughness from about 5 microns to hundreds of nanometres was achieved The microstructure of the surfaces has been studied using atomic force microscopy. Applications of polished fiber surfaces are given.
