The HighLight™ DL HQ series from Coherent are Fiber-coupled Diode Lasers that operate from 900 to 1100 nm. They provide an output power from 2mW to 4mW. These lasers offer a unique combination of high output power and high beam quality from a small diameter (400 to 800 μm) 35m fiber, making them an ideal solution for keyhole welding and other tasks that require the precision application of heat, including surface treatment, cladding, 3D additive manufacturing and brazing. The lasers support plug-and-play fiber exchange (QBH, LLK-HP or QD) by the user, and their web interface (Ethernet) enables simplified access and control through any device with a web browser.
