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 …

This paper presents a comprehensive experimental study of multi-stable-state output
characteristics in an all-fiber laser with an acoustic-optical modulator (AOM) as the Q …

The numerical modeling of actively Q-switched fiber lasers is systematically presented. On
the basis of typical Q-switched ytterbium-doped double-clad fiber lasers under forward and …

An experimental study of self-Q-switching (SQS) in an ytterbium doped fiber laser (YDFL)
arranged using a twin-core GTWave assembly is reported. The main mechanisms that …

An all-fiber actively Q-switched Yb-doped laser is presented. Q-switching is performed by
modulating a fiber Bragg grating via a magnetostrictive rod which is fixed to the fiber at the …

We propose an optimum Q-switching profile for complete suppression of the multi-peak
phenomenon (MPP) without loss of pulse energy in an actively Q-switched ytterbium (Yb) …

In this paper, we report an active Q-switching of an erbium-doped fiber laser with special
modulation functions and novel laser geometry. We experimentally demonstrate that using …

A distributed laser model is applied to explain the multi-peak shape of the pulses generated
by the actively Q-switched erbium-doped fiber laser. In the model, all kinds of intra-cavity …

In this paper, we present a novel stochastic and spatially lumped multi-mode model to
describe the nonlinear dynamics of actively Q-switched lasers and random perturbations …
