| titleOfInvention |
Diffractive optical system with synthetic opening and laser cutting device incorporating this system |
| abstract |
An optical device for focusing a light beam. The device includes a Fourier diffractive element that can separate an incident beam into n beams along n directions which are symmetric about an optical axis. The device also includes a diffractive element including n Fresnel lenses capable of refocusing the n beams onto the optical axis. The device may be used with lasers and laser cutting devices. |
