Abstract
The disclosed ultra-high power all fiber laser system is configured with multiple spaced apart fiber lasers outputting respective laser beams respective paths. The disclosed system is further configured with a tapered fiber-bundle including at least one central guiding fiber and a plurality of peripheral guiding fibers. The disclosed system further has a multiclad delivery fiber configured with a double-bottle neck cross-section and provided with at least two concentric and radially spaced apart inner and outer cores. The inner core is coupled to the peripheral guiding fibers while the inner core is spliced to the central guiding fiber so that a system output emitted from the inner core of the delivery fiber has a different beam shape from the system output emitted from the outer core.
