AI Technical Summary

Problems solved by technology

All of this physical manipulation can lead to structural defects such as microbends in the fiber or cladding, which can cause loss and / or reduction in beam quality or efficiency
In addition, these fibers are difficult to handle due to the twisted fibers required to obtain high coupling efficiencies

Abstract

Disclosed is an optical fiber combiner comprising a coupling device having an input surface area Ain and an output surface area Aout, wherein the input surface area Ain is greater than the output surface Aout, a plurality of optical fibers each having an input surface and an input surface and an output surface, the ouput surfaces of the plurality of optical fibers are coupled to the copuling device, and the coupling device combines optical power emitted by the plurality of optical fibers.

Description

technical field [0001] The present disclosure relates to high power fiber laser systems. In particular, the present disclosure relates to a high power fiber optic system configured to combine multiple fibers into a single output fiber. Background technique [0002] High power semiconductor lasers are used to pump cladding pumped fiber lasers. Fiber lasers are capable of producing output powers in the kilowatt range and are used in a variety of applications requiring high output power, such as cutting, welding, material processing (eg, marking, engraving, and cutting), and directed energy. Achieving the power levels required for these applications is typically achieved by combining the fiber-coupled outputs of multiple low-power diode modules into the pump active fiber. [0003] When combining diode-pumped fibers, it is often convenient to perform the combining of coupled fibers using a fiber-based combiner that couples multiple fibers into a single output fiber. Often, co...
