Abstract (en)
[origin: WO0216969A2] A method of producing in a solid transparent material, a diffractive optical element for the transformation of an incident wave in a predefined manner, by developing a mathematical model of the element in terms of the required transformation, then using that model for determining a set of points which form the desired diffractie optical element, and then focusing a pulsed laser beam sequentially onto the points in the set, such that it causes optical breakdown damage at those points. Numerical solutions for determining the positions of the set of points from the mathematical model are presented. The production of number of elements for specific applications is described. Complete laser systems capable of monitoring the production of the points in real time according to the results obtained by diffraction of the incident wave by the element under production.
