For multi-kW power levels, beam combining has become the method of choice to reach higher powers as needed. This modular approach offers many benefits in terms of building, spare provisioning, and future upgrades. OFS’ TrueM2 Fiber Laser Beam Combiners provide a practical means of scaling with only a few simple splices. OFS’ TrueM2 Fiber Laser Beam Combiners offer two ways to reach multi-kW power levels: You can build with matching TrueMode Fiber Laser Cavities from OFS, or combine your existing fiber lasers with matching output. All TrueMode Fiber Laser Cavity building blocks can be equipped with a single-mode output fiber, ready for direct coupling to a matching TrueM2 Fiber Laser Beam Combiner. This truly single-mode operation helps ensure a low loss connection which reduces instabilities and feedback effects.
