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

✦ Synopsis
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 perspective for technology processes and medicine.

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
## Abstract We report on a all‐fiber actively Q‐switched laser based on a Mach‐Zehnder interferometer (MZI). One of the arms of the MZI is bonded on a piezoelectric transducer (PZT). The path length difference between those two arms will change when a RF electric signal is applied drives the PZT, a
We report an experimental realization and study of a self-Q-switched diode-pumped all-fiber Ytterbium laser. Possible mechanisms leading to establishing of self-Q-switching in the laser are discussed.
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
