Description

High Power Blue Laser Series BL

The NUBURU High Power Blue Laser BL Series is engineered to redefine possibilities in precision, power and versatility within the laser technology landscape. Leveraging advancements in blue laser sources with exceptional beam quality, this series introduces a new standard in performance and reliability.

Properties of BLUE

The utilization of blue laser sources with excellent beam quality ensures better focusability and control of the laser beam. Outstanding absorption in yellow metals like copper or gold make the processes undeniably stable. This leads to increased efficiency in materials processing, reducing waste and enhancing overall productivity.

For all welding types a spatter-
free process is characterizing. This is not only important for typical welding and cutting applications but also for additive manufacturing.

Advantages of High Power Blue Lasers (compared to IR lasers)

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.

  •     Significantly higher absorption: the energy transfer of blue lasers is 2 to 20 times higher as for most materials
  •     Increased throughput: blue lasers deliver 3 to 10 times faster material processing speeds
  •     Higher precision, resolution and manufacturing quality due to wavelength-dependent, improved focusability
  •     Better manufacturing quality due to spatter-free performance in material welding


Applications for the blue laser BL Series

NUBURU_markets

The advantages of the blue wavelength are especially the spatter-free welding of copper and dissimilar metals (Cu, SS, Al, Ni).

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