The HighLight D-Series includes products with output powers of 2.8 kW, 4 kW, 6 kW and 8 kW (all at 975 nm), thus addressing the varying requirements of the worldwide industrial market. The unique design of the compact laser head enables a wide range of output beam size options that won’t restrict application deployment. For example, the 6 kW and 8 kW models are each offered with line beam dimensions of 1 mm width and either 6 mm, 12 mm or 24 mm length. Lower power systems have additional beam lengths of 3 mm, 4 mm, or 5 mm. Furthermore, an optional beam shaping accessory can expand the 1 mm beam width dimension to 3 mm, 4 mm, 5mm, 6 mm, 8 mm or 12 mm.
Various industrial options facilitate ease-of-use of the HighLight D-Series. These include an air knife, which protects the laser from back-splattered material, heat and returned laser light, thus extending system lifetime. A pyrometer for monitoring work surface temperature enables closed-loop control of laser power during heat treatment and cladding. Features to enhance productivity include a laser system control unit with a simple graphical interface, and remote diagnostics that allow system operation to be analyzed by Coherent service personnel over the internet.
