As laser technology matures, the question changes from “what problem can we solve with this laser?” to “what laser parameters do we need for this manufacturing process?” The designs of products ranging from consumer electronics to automobiles require new shapes and features—and these rely on laser technology. To meet the design challenges, the laser industry must deliver appropriate systems with high durability and reasonable prices. For this task, it is microoptics that convert the laser beam from an off-the-shelf source to a custom source of heat distribution needed for a specific process.
