An ytterbium-doped double-clad fiber laser with one-end pumped by four 915 nm laser diodes (LDs) combined by a homemade multimode fused fiber bundle combiner is proposed. The combiner, fused by splicing four fiber pigtails from diodes, exhibits a good capability of low-loss and a high efficiency of 92.7%. The fiber laser, which can generate a continuous-wave (CW) up to 10.3 W output power at 1104 nm with a homemade D-shape inner cladding ytterbium-doped fiber, is demonstrated. The slope efficiency is about 65% and the optical-to-optical conversion efficiency with respect to the pump power is 46% at its maximum output laser power.

“…However, recent years have seen a major breakthrough in this field. Methods have been developed and implemented for entirely fiber-based coupling systems for transferring radiation to/from double-clad fibers [14][15][16] operating with high optical powers. These are multimode fiber couplers with an extra signal fiber (fiber power combiners).…”

Abstract. This paper presents the concept and design of medium to high power fiber radiation sources in MOPA (Master Oscillator Power Amplifier) configuration. Research results are presented on a two-stage power amplifier for MOPA applications for the third telecommunications window at 1550 nm based on active erbium-doped and erbium/ytterbium-doped fibers. The amplifier is fabricated entirely in fiber technology and delivers several watts of output power.

“…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
