Paper Abstract

The wide facilities of optical components forming using the methods of laser treatment of the optical glass and glass-like materials attract attention of many investigators nowadays 1,2,3 Local laser heating controlled in area and time allows to get the materials with a new non-equilibrium structure having the different values of density p and, consequently, the different values of refraction index (RI) ii. RI distribution ti(r) in glass and gi ass-like materials ( mean ceramics,glass-ceramics etc.) defines by the temperature distribution Tfr) , the values of heating and cooling rates in the laser treatment zone (LTZ) and also depends on the physical and thermomechanical properties of sample and its "thermal history".While controffing by laser intensity distribution q(r, t) in the LTZ, by the time of laser action -r and the temperature of preliminary heating of sample T0 we are able to form a different distributions of RI in the local volumes of glass and to control by the surface profile of sample in and near the LIZ.
