Beam Delivery Fibers for Generating Flat-Top Beam Output
Controlling Beam Stability and Uniformity
NuBEAM Flat-Top fibers are specially designed to scramble the mode content propagating in its core, tailoring the mode power distribution to achieve flat-top beams. In addition, these fibers have been carefully engineered to allow precise control of the output beam parameter product (BPP) or beam divergence. Nufern’s flat-top beam delivery fibers offer unique performance attributes to efficiently convert Single-Mode (SM) and Multi-Mode (MM) beams into flat-top beam profiles. NuBEAM Flat-Top fibers are perfectly suited to be easily and efficiently integrated with existing fiber and free-space based optical systems and are designed to handle multi-kilowatt power levels. These unique fibers offer the highest level of performances for laser, amplifier and light delivery systems requiring either flat-top and homogeneous beams, mode mixing or BPP enhancement.
