Laser treatment method for imparting increased mechanical strength to glass objects |
| abstract |
A method for imparting increased mechanical strength to a glass object having imperfections in a surface thereof. The glass object is heated to a temperature above the strain point of the glass. A laser beam is generated having a wavelength absorbable by the glass and impinged on all portions of the surface containing the imperfections. The power density at which the beam is impinged is sufficient to rapidly heat a surface stratum of the glass to establish a thermal gradient therein whereby the viscosity at a depth from the surface sufficient to encompass the imperfections is low enough that the stress induced by the surface tension of the glass at the sites of the imperfections is sufficient to cause flow of glass and effect a reforming of the glass surface at said sites. |
