Laser 2000 launched their blue fibre-coupled laser module, AO-150 by Nuburu at the Advanced Engineering 2017 exhibition, NEC, Birmingham.
Blue light has a number of advantages over infrared lasers in materials processing and 3D printing, such as greater absorption, higher resolution, and increased processing speed.
A large number of non-ferrous metals, such as copper and yellow metals, have up to 20 times greater absorption in the blue region of the electromagnetic spectrum compared to the infrared region.
Blue light can also focus to a significantly smaller spot (up to five times smaller) than infrared light. This improvement on the resolution, combined with greater absorption, provides better control of the processing window and increased processing speed.
