Watch: How Do You Know Your AM Laser is Performing to Spec?

How can you assure your AM laser is performing as needed to produce high quality, consistent builds? Some modern in-situ tools provide a partial picture of the performance of the lasers that are empowering your 3D laser printers, but they often don’t tell the complete story because they capture only a portion of the laser…

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…
