摘要：

In this brief review we consider the relatively new design of the pulsed fiber lasers, namely lasers with the fiber saturable absorber (FSA). Main advantage of this design consists in a possibility to realize a simple all-fiber scheme of Q-switched laser. We show that such lasers can be based on the different types of the fiber absorber and operate in the different spectral ranges. Up to now a set of the pulsed lasers were build. Pulse energy from several mu J to several hundred mu J was demonstrated. Pear power was changed from tens W to several kW with the pulse duration from 50 ns to 1 mu s. We show that described principles of Q-switching can be applied for other types of the fiber lasers. Also, new fiber absorbers are suggested.
