A dual-wavelength laser platform (combined 532nm and 1064nm wavelengths) for welding copper and aluminium for electrical connections in solar cell and battery applications, using fixed and scanning optics. Innovation: Single laser source capable to deliver Green and IR wavelength at the same time. Proportion of Green and IR radiation is set online via pulse shaping. Customers target: - Electronics industry (Ribbon and wire bonding). - Solar industry (thin film bonding). Benefits: - More reliable and reproducible copper welding process. - Higher yield, less pre-processing costs.
