Raycus RFL-ABP (Adjustable Beam Profile) fills the gap in domestic fiber laser beam mode adjustable technology. Using the customized optical fiber combiner developed by Raycus, different modes of output such as Gaussian spot, ring spot, mixed spot, etc. can be realized, which can be switched at will according to processing requirements. At the same time, the power of the fiber core and the ring core can be adjusted independently to achieve any power ratio between the fiber core and the ring core. Meeting the needs of high-quality laser cutting and welding has become another weapon to improve processing quality and efficiency.
