Corelase debuts versatile 8kW fiber laser

Tampere, FinlandCorelase, the Finnish subsidiary of industrial laser firm Rofin-Sinar that specializes in fiber lasers, is introducing a new 8kW source at the LASER World of Photonics trade show (June 22-25, 2015, in Munich, Germany).

The ARM system promises not just high power—it will enable “a new era” for fiber laser material processing, thanks to its highly adaptable design. ARM stands for adjustable ring mode and can be used to alter the laser beam’s power profile on the fly, a feature that could offer customers the option of buying a single, universal laser tool to perform tasks that would currently require several different ones.

One of the key benefits of the design is its suitability for processing any kind of metal, regardless of its reflectivity—more reflective metals like copper and aluminum can cause problems with conventional laser processing systems. This laser is equipped with a five-step back-reflection resistance system, which enables processing of sensitive and tough materials with protection against back-reflection caused by processing highly reflective materials.

The beam-shape flexibility and inherent versatility of the system means that it can be used for laser additive manufacturing as well as more traditional applications like welding, cutting, and drilling.

The power output of up to 6kW is possible at the inner spot, with 8 kW at the outer ring. However, the standard specification would offer a combined power of 8kW in total.
