Abstract
Many micro system devices such as computer hard disk drives or micro-optical structures are crucially depending on the precise alignment of specific lenses, sensors or other functional components. The problem of meeting the tight positioning tolerances represents an up-to-date key assignment in ultra precision manufacturing and assembly. Instead of individual, high-precision manufacturing of each component, its accurate adjustment after assembly has turned out much cheaper and easier to perform. The components themselves and most of the process steps during assembly are in this case allowed to possess loose tolerances because the precise adjustment of all critical components is performed later in a separate process step. Unlike most other alternatives, laser driven alignment processes represent a very elegant and convenient way to manipulate mounted components in a micron and submicron range. As miniaturized devices are typically difficult to access and highly sensitive to mechanical forces and impacts, especially applications in micro technology benefit from the general advantage of laser adjustment processes to allow a completely contact free interaction. Moreover, the laser offers unmatched flexibility and controllability as well as ideal adaptability to the process and the application. As all established laser adjustment processes are based on thermally induced stress and therefore limited in both accuracy and applicable actuator materials, new nonthermal adjustment mechanisms using ultrashort laser pulses have been investigated and theoretically and experimentally demonstrated. This contribution will therefore both give latest scientific information on novel laser forming mechanisms and focus on possible applications for the near future in the field of micro manufacturing and assembly.
