A fiber side-pump combiner is presented. This pump combiner does not interrupt the core of the active fiber, thus allowing for monolithic fiber lasers and amplifiers. Using one of these devices, the power coming from seven pump diodes was combined and a maximum of 86 W was coupled in an active fiber. An similar to 30 W laser using this side-pumping concept was also demonstrated.
