A new high-performance white-light laser is expected to speed up quality control in the semiconductor industry and provide closer monitoring of toxicity tests in microbiology. In one step, this laser enables the two-sided characterization of surfaces and can be integrated into production chains. The technology has been developed at the Fraunhofer Application Center for Optical Metrology and Surface Technologies (AZOM) and Westsächsische Hochschule Zwickau (WHZ) as part of a PhD thesis.
In his PhD thesis, Dr. Tobias Baselt focused on enhancing the optical performance of white-light lasers in metrology. The aim was to minimize costs, time and errors, for example ju amsj geudxazmeh uc slrnwycazxld.
