Fiber lasers have made remarkable progress over the past three decades, and they now
serve farreaching applications and have even become indispensable in many technology …

In this work, the impact of fiber bending and mode content on transverse mode instability
(TMI) is investigated. Based on a modified stimulated thermal Rayleigh scattering (STRS) …

In this paper, we established a high power tandem pumped fiber amplifier based on tapered
ytterbium-doped fiber (TYDF). The TYDF is developed in-house with a core/inner cladding …

The high absorption confined-doped ytterbium fiber with 40/250 μm core/inner-cladding
diameter is proposed and fabricated, where the relative doping ratio of 0.75 is selected …

We report on what we believe is the first demonstration of a monolithic counter tandem
pumped ytterbium-doped fiber amplifier based on conventional double-clad fiber. At the …

In this paper, we demonstrated a high-brightness bidirectional tandem-pumped confined-
doped fiber amplifier with nearly 8 kW output power. The technical difficulties for realizing …
