Abstract

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