The 450 nm laser AO-650 is a water-cooled diode laser with 650 W output power. The diodes are coupled into a 400µm fiber with a QBH termination. The laser operates in cw mode and can also be modulated with up to 500 Hz. Especially suitable for battery production and because the copper welding with lasers.
This new generation of blue laser diodes was developed for micro and macro material processing of copper and its alloys as well as for nobel metals. Several high reflective metals have a limited absorption in the IR and the green wavelength. In this spectral width the blue wavelength has significant advantages.
By a microscopic and macroscopic inspection of the welding spot the homogeneous liquid phase of the weld pool shows a more wax-like behaviour than the common well known one of metals.

The application-oriented platform of blue high-power lasers will be changing the metal welding of non-ferrous metals, as well as the additive
manufacturing production decisively.
The advantages of the blue wavelength are especially the spatter-free welding of copper and dissimilar metals (Cu, SS, Al, Ni).
