Laser Applications in EV Car Batteries

Electrical cars are all around us. The power source of an electrical car is its Li-ion battery pack. One of the most important parameters for a battery pack is its charge capacity per weight in kWh/kg.  This means that battery and car makers want to put in as many ‘battery cells’ (the basic Li-ion unit…

Watch: Laser Measurement Solutions for Material Micro Processing Applications

If you use lasers in material “micro processing” applications – such as drilling via holes in PCBs, OLED display “lift-off”, cutting of smartphone cover glass – you already know how difficult the challenges are. The often delicate combination of laser parameters – ultra short pulse duration, high repetition rate, perhaps short wavelength among others –…

Green and Blue Laser Welding

Laser welding, cutting, or cladding has become increasingly popular and, in most cases, has been performed at the NIR wavelength region. However, NIR lasers are less efficient for copper processing due to hig­h reflectivity and therefore low energy absorption. Copper absorbs just 5% of the laser energy at 1070nm, but up to 40 % at…

Not Too Hot, Not Too Cold: Sensor Fusion Analysis in Additive Manufacturing Laser Processing

Sensor fusion is a concept that merges – or fuses – data from various sensors to create a more complete understanding of a laser’s performance. It’s particularly important in additive manufacturing using laser powder bed fusion, a 3D printing process that makes metal parts. Metal powder is subjected to powerful laser beams, creating solid layers…
