Glass comprising at least one material, as a heat source material for absorbing and converting a laser beam to heat, selected from Ni, Fe, V, Cu, Cr, and Mn and added to a glass matrix comprising at least one glass forming oxide selected from SiO2, GeO2, B2O3, P2O5, TeO2, Ga2O3, V2O5, MoO3, and WO3 and at least one material selected from alkali metals, alkaline earth metals, rare earth elements, and transition elements is provided. A laser beam with a wavelength capable of absorbing the heat source material is applied to the surface and/or inside of the glass to convert the exposed part to a single crystal or a group of crystal grains free from the heat source material and comprising components contained in the glass matrix and thus to form a pattern. Thus, an optical component having excellent secondary optical nonlinear properties is obtained.
