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 …

Abstract Bismuth selenide (Bi2Se3), a new topological insulator, has attracted much
attention in recent years owing to its relatively simple band structure and large bulk band …

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 …

A pulsed regime of short-cavity, heavily erbium-doped fiber lasers is of high interest for its
possible applications in telecommunications and sensorics. Here, we demonstrate and …

We demonstrate all-fiber dual-wavelength Q-switched and mode-locked erbium-doped fiber
laser (EDFL) by utilizing the thulium-holmium-doped fiber (THDF) as a fiber saturable …

Generation of ultrashort pulses in an all-fiber Erbium-doped fiber laser (EDFL) cavity with
doped fiber saturable absorber (DFSA) is demonstrated for the first time. The doped fiber …

A detailed comparative study of heavily erbium-doped fiber laser generation features was
carried out in the case of 1490 nm and 976 nm wavelength pumping. The laser cavity was …

We propose and demonstrate a novel method to achieve pulsed operation of thulium-doped
fiber lasers at 1.7 μm. In our design, the thulium-doped fiber laser cavity was embedded …

We demonstrated a reliable and stable Q-switched ytterbium-doped fiber laser centered at
1069 nm by employing a segment of 11 cm thulium-doped fiber (TDF) as a saturable …
