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 …

A Q-switched ytterbium-doped fiber laser (YDFL) is proposed and demonstrated using a
newly developed multi-walled carbon nanotubes polyethylene oxide (MWCNTs-PEO) film as …

Using the rate equations and their stability analysis, an algebraic model has been
developed to predict the values of characteristic magnitudes of the output of a laser …

We report an efficient high-peak-power and high-average-power passively Q-switched
ytterbium fiber laser with a Cr^ 4+: YAG crystal as a saturable absorber in an external …

Using an ytterbium-doped fiber with a 50 μm core and 0.028 NA, a pulse energy of 4.8 mJ
was achieved directly from a single-mode Q-switched fiber laser. The repetition rate was 10 …

The gain-switched fiber laser presents the simplest construction among pulsed lasers in the
nanosecond region and consequently is also very robust. These properties make it …

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) …

We report a design for a power-scalable all-fiber passively Q-switched laser that uses a
large mode area Yb-doped fiber as a gain medium adiabatically tapered to an unpumped …

We demonstrate a stable passively Q-switched and gain-switched Yb-doped all-fiber laser
cladding-pumped by a continuous fiber-coupled 976 nm laser diode. By use of an all-fiber …
