The laser-induced metal sphere implantation into glass

Metal doping in glass can change the properties of glass. A metal foil placed in direct contact with one side of the glass substrate. Continuous-wave (CW) laser illumination can implant metal spheres by heating the metal foil. In this study, the laser heating conditions required to implant metal spheres into glass are investigated experimentally and theoretically. The temperature of the glass exceeded the temperature threshold of laser absorption when the metal sphere was implanted. In addition, sphere implantation speed increased with the laser power density. The metal sphere was implanted at speeds of 20 to 50 mm/s.
