LASER World of PHOTONICS 2011 will present ultra-short pulsed lasers for micromaterial processing
New laser systems are making processes less energy-intensive and more accurate. In many cases innovative lasers enable certain production steps to be carried out, especially when micromaterial processing is involved – i.e. drilling, milling and cutting in the microscopically small range. The lasers used in this processes do not emit light continuously, they are “pulse” operated, i.e. they emit their light in time-limited, very short “puls...
