Abstract

Cladding pumped fibre lasers have been rapidly researched and developed with help of semiconductor laser diode bar and stack. Especially these fiber lasers showed a high power conversion efficiency of about ~80% in case of Yb-doped double clad fiber laser and a high-quality beam of M²= 1. Output power of a fiber laser is determined by how much a pump light can be intensely coupled into an inner cladding layer of a double clad fiber. In this paper, we introduce an efficient pump beam combiner based on single mode fibres.
