Rofin-Baasel UK Ltd. has announced the FL series high-power fiber lasers. The FL ×75 and FL 010 output 750 and 1000 W, respectively. The beam can be coupled with 50- to 600-μm-diameter fiber optics, resulting in beam quality of 2.5 to 30 mm × mrad. The lasers can be used to weld small parts with low thermal distortion and minimal heat-affected zones, and steel and aluminum can be joined with welding depths of several millimeters. The optional beam switch and energy-share modules enable a single laser to be used in up to four work cells.
