Niklaus Ursus Wetter graduated in Physics at the Swiss Federal Institute of Technology in Zürich (Eidgenössische Technische Hochschule Zürich) in 1988 and received his PhD in 1993 from the Institute for Energetic and Nuclear Research at the University of São Paulo (IPEN/SP). He is head of the Laser Development Lab at the center of Lasers and Applications (CLA) of IPEN/SP and Division Head of Laser Materials Development. His research interests are diode-pumped solid-state Lasers (DPSSL) with emphasis on spatial and spectral control and resonator design. He has a tradition in working with fluoride solid-state laser materials, especially YLiF4, but he also researches new laser materials and is specialized in material spectroscopy and computer simulation. The development of tailored light sources, especially for medical and dental application, is another area of interest. Since 2008 he develops light sources in disordered materials for applications in photonic devices. From 2013 to 2018 he was the director of the Center for Lasers and Applications at IPEN/SP in the University of São Paulo. He has six patents and his articles have been cited more than 1700 times and his h-factor is 24 (Scopus). (Source: Lattes Curriculum)
