Abstract
To obtain an optical component having excellent secondary optical nonlinear properties by irradiating a surface and/or inside of glass having at least one member selected from Ni, Fe, V, Cu, Cr and Mn as a heat source material for absorbing and converting a laser beam to heat, incorporated to a glass matrix comprising at least one glass-forming oxide-selected from SiO, GeO, BO, PO, TeO, GaO, VO, MoOand WOand at least one member selected from alkali metals, alkaline earth metals, rare earth elements and transition elements, with a laser beam with a wavelength to be absorbed by the heat source material, to convert the irradiated portion to a single crystal or a group of crystal grains comprising components contained in the glass matrix and not containing the heat source material, thereby to form a pattern.
