<p><P>PROBLEM TO BE SOLVED: To provide a processing method and a processing device of diamonds, capable of processing and cutting a diamond main body to a linear or planar shape without influencing the diamond main body. <P>SOLUTION: A high-harmonic conversion of a laser beam 21 from an LD excited near-infrared laser 11 is carried out with a high-harmonic converter 12 to obtain a wavelength-converted laser beam 22 with a wavelength of 266 nm; and the wavelength-converted laser beam 22 with a wavelength of 266 nm is converted into a scan laser beam 23 with a galvano-scanner 14 and converged with a circular fθlens 13, thus condensed as a convergence laser beam 24. The convergence laser beam 24 is charged into diamond 15 and absorbed by solid solution nitrogen contained in diamond 15; and thermal energy processing of the diamond 15 is carried out by ablation and evaporation. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
