Where am I?
Ultrafast lasers are becoming increasingly popular not only in science and research, but also in industry.
High lateral resolution due to precise focusability down to a few micrometers, low heat input and high flexibility are main features of laser tools and processes for precision structuring and surface functionalization.
Lasers can be used to drill holes ranging in diameter from several millimeters to less than one micro-meter.
To reach this goal, laser processes will play an important role in the production of modern solar cells.
