“…Figure 1b shows pumping by fused fiber bundle with tapered bridging fiber. In this case the input fiber bundle is fused and spliced with a bridging (intermediate) fiber which then is tapered down and spliced to an output DC fiber [24]. Figure 1d presents the most common tapered fused bundle (TFB) power combiner scheme, where the input fiber bundle is fused (e.g., after placing it inside the capillary tube), tapered down, cleaved, and spliced to the DC fiber [13][14][15][16]25,26].…”

The most important components for application in high-power all-fiber lasers and amplifiers are, most of all, power combiners, but also mode field adaptors. This paper summarizes recent achievements in the area of development and fabrication of high-power passive fiber components. The principles of operation and basic design and fabrication criteria, which have to be taken into account while designing the aforementioned components, are explained in detail. The most recent impressive achievements are summarized and described.

“…Such components have been commercially available for several years for the polymer cladding fibers, [31][32][33] but only recently have they been demonstrated in all air-clad fiber-based designs. 34 The airclad pump/signal combiner is based on a 7 + 1 to 1 configuration that features a 15 μm MFD signal feedthrough and is used for pulse amplification in a backward pumped configuration.…”

Abstract. High-power fiber lasers and amplifiers have gained tremendous momentum in the last 5 years. Many of the 0091-3286/2011/$25.00 C 2011 SPIE traditional manufacturers of gas and solid-state lasers are now pursuing the fiber-based systems, which are displacing the conventional technology in many areas. High-power fiber laser systems require reliable fibers with large cores, stable mode quality, and good power handling capabilitiesrequirements that are all met by the airclad fiber technology. In the present paper we go through many of the building blocks needed to build high-power systems and we show an example of a complete airclad laser system. We present the latest advancements within airclad fiber technology including a new 100 μm single-mode polarization-maintaining rod-type fiber capable of amplifying to megawatt power levels. Furthermore, we describe the novel airclad-based pump combiners and their use in a completely monolithic 350 W cw fiber laser system with an M 2 of less than 1

“…Fused fiber-based combiners for coupling pump and signal light into active fibers are essential components for making fiber lasers and amplifiers [1][2][3][4][5]. These combiners typically have a tapered section that increases the intensity of the pump by reducing the pump guide area.…”
