Product description


1. High Power Blue Lasers AO-200

The 450 nm laser AO-200 is a water cooled diode laser with 200 W output power. The diodes are coupled onto a 200µm fiber with a SMA termination. The laser operates in cw mode and can also be modulated with up to 50 kHz.

2. Properties of the blue AO-200 laser

The new generation of blue laser diodes was developed for micro and macro material processing of copper and its alloys as well as for noble 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 high-power blue laser will radically change the process and quality during cutting, welding and additive manufacturing.

3. Advantages of a NUBURU blue laser (compared with an IR laser)

The applied platform of blue high poweredfgsdfgs lasers will crucial transform the metal cutting and welding as well as the additiv manufacturing.

  • significant higher absorption -> the energy transfair of blue lasers is 2 to 20 times higher for most materials 
  • blue lasers allow a 5 to 20 times faster material processing speed -> higher performance
  • blue lasers have a 5 times smaller spot -> allows higher precision, higher resolution and better production quality (i.e. in 3D printing).
  • unique spatter-free welding performance -> ensures a better production quality

4. Applications for the blue laser NUBURU AO-200

The advantages of the blue wavelength are especially the spatter-free welding of copper, its alloys and noble metals.

  •     micro material processing
  •     welding of foils (i.e. for batteries)
  •     welding of electric/electronic components
  •     additive welding and surface structuring
