Variable disk laser for optimized micro machining

Since many years shortening of pulse duration down to femtosecond regime is propagated as a recipe for achieving higher precision in micro machining with lasers. The drawback of this approach is a loss in productivity which cannot be accepted when large work pieces such as rolls, cylinder liners or solar panels have to be treated. A novel development tool based on disk technology will be presented allowing finding application specific highest productivity at still acceptable inaccuracy.
