Q-switching of fiber lasers using bulk elements has important drawbacks as reduced mechanical stability and high insertion losses. The development of efficient all-fiber modulation techniques is the key to obtain robust, compact and efficient Q-switched all-fiber lasers. Certainly, the development

β¦ Synopsis
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 Qswitched 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 ΞΌJ to several hundred ΞΌJ was demonstrated. Pear power was changed from tens W to several kW with the pulse duration from 50 ns to 1 ΞΌs. We show that described principles of Q-switching can be applied for other types of the fiber lasers. Also, new fiber absorbers are suggested.

Here we demonstrate active mode-locking (ML) and doubly-active Q-switching mode-locking (QML) of erbiumdoped strictly all-fiber lasers. The active ML mechanism relies in the acoustooptic superlattice modulation (AOSLM) effect induced when longitudinal acoustic waves are launched along a fiber Bragg
For the first time we have suggested and realized all-fiber Q-switched Ho-doped laser with the fiber saturable absorber based on the heavily Ho-doped fiber. Two oscillation modes were observed. One of them allows one to obtain pulses with the duration of 20 ns and the peak power as high as 2 kW. Sec
For the first time we have suggested and realized passive Q-switched cladding pumped Er-doped fiber laser with a saturable absorber based on Tm-doped fiber. The pulse duration was of 100 ns, the pulse energy -0.35 mJ, the peak power -3.5 kW while the average power is less than 1 W. The laser is pers
A xenon ash-lamp-pumped, passively Q-switched Nd:GdVO4 laser with GaAs semiconductor saturable absorber is demonstrated. The static laser performance is investigated and the static output is 52 mJ when the pump energy is 9:45 J. The dynamic laser has the highest slope e ciency when the GaAs wafer is
Compared with a single passively Q-switched laser, a double passively Q-switched laser with a GaAs saturable absorber and a Cr 4+ -doped saturable absorber can produce more symmetric and shorter pulses with high pulse peak power. New normalized coupled rate equations for a double passively Q-switche
