High Power Fiber Laser System with High Quality Beam |
摘要 |
A high power fiber laser system has a combiner configured of a plurality of single mode (SM) fibers which are fused together so as to define an output end of the fiber combiner. The fused SM fibers radiate respective fiber outputs, which collectively define a multimode (MM) combiner output. The SM fibers each are configured with such an optimally small numerical apertures (NA) that the MM combiner output is characterized by a minimally possible beam quality factor (M2) for the plurality of SM fibers. To reduce the possibility of burning of the components of the fiber laser system with a multi-kilowatt combiner output, a coreless termination block is fused to the output end of the fiber combiner and configured so as to provide expansion of the combiner output without modifying the minimally possible M2 factor thereof. |
