Paper Abstract

The double-clad fiber laser is a novel one with high-efficiency. It has many advantages such as narrow line width and tunable, good beam quality and compact configuration. It can be widely used in optic communications, optic sensor, optic measurement, etc. In this paper, the principle and experimental results of double-clad Yb3+-doped fiber laser are reported. This kind of laser is pumped by a high power semiconductor laser array and coupled by a set of lens. The laser output of 209mW at 1.0872μm is obtained with a pump threshold of 192mW. The slope efficiency is 49%.
