Virtual workshop series "Follow the light" presented by asphericon and fo+
Jena, January 2021: When classical optics have reached their limits, freeform optics enable what is physically feasible possible and open up completely new horizons in many areas, such as laser material processing, life science, automation and sensor technology.
In close cooperation with the freeform optics cluster fo+ (freeform optics plus) - an association of scientists, developers and manufacturers - asphericon, OSIM (Otto Schott Institute of Materials Research) and ifw Jena will present insights into current research results around the use of freeform optics for laser material processing on February 23, 2021.
Beam shaping is especially suitable for laser material processing, such as cutting, welding and marking in the field of micro- and macro machining. Although Gaussian intensity distributions can be used to realize small structure sizes by direct material removal, there are weaknesses regarding removal depth and quality. In laser welding, on the other hand, the Gaussian profile favours focusability, resulting in a higher welding speed. However, this favours melting on the specimen surface, which increases the risk of spatter build-up.
In cooperation with Otto Schott Institute of Materials Research (OSIM) and ifw Jena, asphericon will present latest results from joint research projects. The presentation will focus on various tailored intensity distributions based on freeform optics with regard to their suitability for micro- and macro-laser material processing. On the one hand, the micro and nano range is addressed when femtosecond lasers are used for cutting, marking and structuring surfaces. On the other hand, we also discuss laser powers of several kilowatts for welding and cutting.

Nine leading Thuringian Photonics companies and two prestigious research institutes have teamed up in the »Innovative Regional Growth Core« fo+ (freeform optics plus) to develop and market innovative freeform optical systems. The project started in 2014 and was initially scheduled to run for three years but extended for further three years in 2018. Highlight of the collaboration so far has been the awarding of the Stifterverband der Deutschen Wissenschaft "Research in Collaboration" science prize for innovative approaches to free-form manufacturing in 2018.
