Abstract

High power fibre lasers and amplifiers are becoming a firm alternative to conventional solid state lasers for operation in the regions of 1 and 1.55 µm. There are a wide variety of applications for these devices in fields such as telecommunications, medicine, material processing and defense. Both continues wave (CW) and Q-switching operation are interesting for different applications. High intensity, high power, high energy pulses; prevention of nonlinear effects and fibre facet damages are also among the challenges. In this talk, we will present results of our work on Yb and Er/Yb-doped high power cladding-pumped fibre lasers. For CW operation, a very simple configuration was set-up. The pump source consists of a broad-stripe diode with nominal output of 60 W at 915 nm. The output of pump source was launched to the fibre using a beam-shaping technique. Reflection from the flat fibre ends is enough to initiate lasing. The output power is taken from both ends of the laser
