One of the nanosecond pulse output strategies for fiber lasers with controlled frequency is
active Q-switching. Low-cost, high-power efficiency, stable cavity, and customizable pulse …

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

We report on aluminum oxide nanoparticles (Al_2O_3 NPs) as a saturable absorber (SA) for
passively Q-switched erbium-doped fiber laser (EDFL) operating at a wavelength of 1560.6 …

We present an experimental study of the dynamics of a high power Yb3+-doped double-clad
fiber laser in various optical configurations operating in the 1.08 μm wavelength. The fiber is …

We investigate the dynamics of a high power unidirectional Yb-doped fiber ring laser with an
intracavity polarizer placed between two halfwave plates. We show that, depending on the …

Intracavity supercontinuum generation based on self-Q-switch assisted by stimulated
Brillouin scattering is experimentally demonstrated from an all-fiber Ytterbium laser in the …

We have designed and performed an experiment that permitted direct observation of
Brillouin backscattering in an Yb-doped double-clad fiber laser. Fifteen Brillouin-shifted …

Backward light scattering can cause passive Q switching in fiber lasers. We propose a self-
consistent description of the laser dynamics. Our model quantitatively reproduces the …

An actively Q-switched all-fiber laser based on an acoustically modulated fiber attenuator
