Paper Abstract

In this paper, it is discussed relationship between the beam quality factor and high order mode in fiber laser, and the relationship between the divergence angle and the beam quality factor. An aperture with adapted diameter in cavity could introduce low loss for the fundament mode but high loss for high order modes. In this method, it is easy to realized mode-selection. By using this method, experiment demonstrated that 23.4W output from a single fiber laser with 1.20 of M2 is obtained.
