Abstract
Abstract In a process for bonding synthetic single crystals which are of the same crystal system and either or both of which have anisotropic characteristics and can transmit light including visible light within a wavelength region in which their assimilative faces are cut to have assimilative physical properties, are optically polished, and made to optically come in contact. The synthetic single crystals are then uniformly heated and cooled gradually or repeatedly heated and gradually cooled to cause an interface reaction at the optically contacting faces to produce an artificial lattice defect.
