ABSTRACT:
Diamond is subjected to working such as smoothing or cutting by irradiation of light having a wavelength in the range of 190 nm to 360 nm to the surface of the diamond. The energy density of the incident light, the divergent angle of the light beam and the half-width of spectrum of the light are specified. The light beam is converged by a cylindrical lens. Moreover, the working is conducted in a specified material, whereby the flatness of the worked face and the working speed are improved.
