Fiber laser with adjustable pulse duration enables new ablation processes P2 and P3 in the production of CIGS photovoltaic modules When producing thin-film photovoltaic modules, coating processes and ablation processes, here the writing of lines, are carried out alternately on a glass plate. This is how the individual solar cells are created with the two electrodes at the top and bottom and the photovoltaic layer in the middle

Light can not only be used to measure, heat and remove material, it can also be used to create structures. The two most common processes are laser sintering or laser stereolithography, in which a 3D structure is created layer by layer. During sintering, powder is heated locally using a laser beam until it melts in a targeted manner. Macro laser stereolithography

Raman spectroscopy Two different Raman spectrometer systems are available for structural analysis of materials. On the one hand, a large laboratory system from Renishaw with three different laser excitation wavelengths (532nm, 632.8nm and 785nm), high transmission and high spectral resolution. On the other hand, a fiber-coupled compact Raman spectrometer (at 532nm excitation) for quick overview spectra. Laboratory Raman spectroscopy The Raman spectrometer from Renishaw is particularly characterized by its
