The mid-infrared (MIR) represents a large portion of the electromagnetic spectrum that is
progressively being exploited for an enormous number of applications. Thermal imaging …

Power scaling of fiber lasers is challenged by several factors, such as the brightness of the
pump source, the nonlinear effect, modal instability, and so on. Pumping active fibers with …

We present review on recent progress on high power Yb-doped fiber laser in a variety of
oscillation spectral ranges. According to Kurkov (Laser Phys. Lett. 2006), the oscillation …

We report a tunability study of a mode-locked Yb-doped self-similar fiber laser. The center
wavelength is tunable from 1030 to 1100 nm without losing mode locking by adjusting a …

The emission band of holmium-doped silica fibers extends beyond 2200 nm, which means
these lasers have the potential of covering considerable parts of the atmospheric …

An ytterbium-doped photonic bandgap fiber amplifier operating at the long wavelength edge
of the ytterbium gain band is investigated for high power amplification. The spectral filtering …

A 100 W-class all-fiber linearly-polarized single-mode fiber laser at 1120 nm with an optical
efficiency of 50% was demonstrated. The laser consists of a 4.2 m long Yb-doped …

BACKGROUND Many modern-day laser systems require nonlinear optical (NLO) elements.
For example, NLO elements are commonly used in applications such as frequency mixing …

We report a high-power high-efficiency single-mode all-fiber Raman fiber laser (RFL)
operating at 1173 nm. With the core pumped by a 144-W 1120-nm Yb-doped fiber laser, an …

Stimulated Raman scattering (SRS) effect is considered to be one of the main obstacles for
power scaling in general-type fiber lasers. Different from previous techniques that aim at …
