  • Method and apparatus for repair of defects in materials with short laser pulses
    Patent number: 6878900
    Abstract: A method of accurately and precisely providing desired functionality to an electronic or opto-electronic component is disclosed in which a Femtosecond laser pulse is used to ablate material from a surface of or from within a component. The component is in active operation during the ablation process in order to facilitate the ablation process. The process also involves detection and feedback to indicate when a repair is sufficiently complete. The detection is also performed while the component is powered allowing in-situ detection and ablation. Of course, forms of facilitation other than feedback such as monitoring are also applicable to the invention.
