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…
