HighLight FL-ARM

HighLight FL-ARM (Adjustable Ring Mode) laser is a unique fiber laser that delivers a significant advance in fiber laser processing by enabling unprecedented solutions, such as zero-gap welding of zinc coated steel and spatter-reduced welding of metals, to name a few.

Improve fiber laser weld quality and yield with CleanWeld

Coherent CleanWeld is our unique combination of fiber laser innovations, beam delivery, and process knowledge, which improves part quality, increases throughput, and lowers process costs. Weld zero-gap galvanized steel, stainless steel, copper, and aluminum with up to 80% less spatter, lower porosity, and no cracking.

Industrial High Power Welding and Cutting Laser

The ARM technology provides two independently controlled co-axial beams from one fiber, leading to a new level of flexibility for demanding applications. The power levels in both central spot and surrounding ring are independently adjustable. This results in high speed and high throughput spatter-free processing and lowers overall production costs by largely eliminating the need for post-processing.

HighLight FL-ARM systems can be configured with one to four separate fiber laser units, thus providing total maximum output powers from 2.5 kW to 10 kW. Additionally, the power in the center and ring can always be adjusted on demand, and even modulated at repetition rates up to 5 kHz. All this makes it easy for both, the system integrators and end users, to achieve exactly the results they need for virtually any processing task. Added to this is a multi-stage back reflection immunity that enhances laser reliability and lifetime, and enables processing of highly reflective materials, including brass and copper.
