| titleOfInvention | Diffractive optical component and laser processing device using the same |
| abstract | A conventional diffractive optical component (DOE) has a unit pattern の of a fixed pattern repeatedly arranged vertically and horizontally and has the advantage that it can be calculated by fast Fourier transform, but the direction of the diffracted light is discrete and predetermined. Appear only in the direction of the lattice point. Kind Code: A1 A transmittance t mn is given to all pixels (m, n) constituting a DOE, and all Fourier transform expressions in desired directions α and β are calculated. Although the amount of calculation increases, an irregular diffraction pattern off the grating can be generated. Further, the resolutions U and V can be set to values smaller than λ / aR and λ / bS (λ is the wavelength, aR and bS are the sizes of the DOE). It is possible to split a laser beam into arbitrary directions and numbers with high resolution. It is possible to irradiate a laser beam to an arbitrary position at a multi-point collectively with high positional accuracy. A free and highly accurate spot arrangement required for electronic components can be realized. This has a great effect on speeding up laser processing and cost reduction. [Selection] Fig. 2 |
