The Q-switching characteristics of actively Q-switched fiber lasers, especially the
inconsistency of experimental observations with traditional Q-switching theory, are reviewed …

Wavelength beam combining of five ytterbium fiber lasers is demonstrated in a master-
oscillator power-amplifier configuration at combined powers up to 6 W. The combined beam …

Efficient repetitive passive Q switching of a cladding-pumped Er–Yb fiber laser has been
demonstrated by use of an external-cavity configuration containing a Co^ 2+: ZnS crystal as …

The famous demonstration of optical rogue waves (RWs), a powerful tool to reveal the
fundamental physics in different laser scenarios, opened a flourishing time for temporal …

We present results on a high-power, cladding-pumped, Yb-doped fiber emitting at 977 nm in
laser and ampllified-spontaneous-emission source configurations. We obtained up to 1.4 W …

The effect of broad-range (16 nm) self-sweeping of a narrow-line (less than 1 pm) Yb-doped
fiber laser has been demonstrated experimentally. It is found that the effect arises from the …

A new effect for a CW-pumped ytterbium fiber laser (YFL), self-induced laser line sweeping
(SLLS), is reported. The effect's main characteristic is``adiabatic''movement (seconds) of the …

A high-power and high-repetition-rate passively Q-switched ytterbium-doped single-mode
double-clad fiber laser was built using a Cr 4+: YAG saturable absorber (SA). Two different …

We propose a novel scheme for suppressing stimulated Brillouin scattering in optical fibers.
The scheme makes use of a single or a sampled Bragg grating fabricated within the fiber …

We describe the design and characterization of a tunable narrow linewidth thulium-doped
fiber laser source which combines a core-pumped preamplifier and high power cladding …
