In this paper we explore different beam-combining strategies based on tapered fiber bundles, aiming to increase the brightness of pump sources for double-clad fiber lasers and amplifiers. We consider single-stage N 1 combiners with tapering and fusing of a conventional MM fiber bundle as well as multistage cascades of such N 1 combiners.

A tapered fiber bundle series power combiner for combining several multimode sources into one fiber, with standard configurations of 3x1 and 7x1. Fabricated using G&H proprietary controlled fusion process the combiner enables high coupling efficiency over a wide wavelength range.

Tapered fiber bundles are often used to combine the output power of several semiconductor lasers into a multimode optical fiber for the purpose of pumping fiber lasers and amplifiers. It is generally recognized that the brightness of such combiners does not exceed the brightness of the individual input fibers.

We investigate a 19×1 tapered fiber bundle(TFB) pump combiner based on twist method. To our best knowledge, this is the first time 220/242 μm multimode fibers act as pump fibers for a 19×1 pump combiner.

A process of fabricating tapered fiber bundle (TFB) consisting of a set of input pump fibers, stacked inside a low-OH silica capillary, has been optimized to combine multiple multimode pump powers into different output fibers having cladding diameters of 400, 250, and 125 µm.

We demonstrate two types of tapered fiber bundle (TFB) end-pumping combiner able to combining multi-kilowatts of pumping laser. After the experimental test of coupling performance, the 3×1 coupler is proved to have a power handling capacity of 2.11 kW with a coupling efficiency of 95.1%, and the 7×1 coupler is capable of handling pumping ...
