The 450 nm laser AO-200 is a water cooled diode laser with 200 W output power. The diodes are coupled into a 200µm fiber with a QBH termination. The laser operates in cw mode and can also be modulated with up to 50 kHz. It is particularly suitable for copper welding with lasers, for example in battery production.
The 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 absorbtion in the IR and the green wavelength. In this spectral width the blue wavelength has significant advantages. In 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).
