Abstract

The Q-switched fiber lasers are very attractive sources in many applications such as military affairs, surgical operation, laser machining, laser marking, nonlinear frequency conversion, range finding, remote sensing and optical time domain reflectometer. To improve the pulse energy of Q-switched fiber laser is what we pursue. In this paper, certain effective methods to improve the pulse energy are presented, with their theoretical basis clarified, which may be helpful to the design of the kindred Q-switched fiber lasers..

Keywords
