At Compamed 2011, ROFIN showcased the latest developments in laser material processing. The focus was on manual laser welding and high-precision cutting with ultra short pulse femto / fiber laser sources for medical device manufacturing. Within a few months, ROFIN's newly designed manual welding ...
