Supercontinuum generation in large mode-area microstructured fibers

Optics Express, 2005
Supercontinuum generation in large mode-area microstructured fibers is demonstrated by launching into the fiber ns pulses from a passively Q-switched Nd:YAG laser. The special properties of these fibers open the way to compact, single-mode, high-power supercontinuum sources with a low divergence of the output beam.

Large mode area fiber lasers and their applications [PDF]

Advanced Solid State Lasers, 2000
The area of fiber lasers has undergone rapid developments in recent years. Gone are the days when fiber lasers were seen as something of an irrelevant curiosity, offering interesting performance features, but always with power levels or other performance limitations, that made them unsuitable for all but a few applications.

Bendable large-mode-area fiber with a non-circular core [PDF]

Applied Optics, 2018
We investigate mode-area-scaling and bending performances of a Yb-doped large-mode-area fiber with an elongated non-circular core. Such fiber can be bent in the plane of its short axis to suppress bending effects, such as mode area reduction and mode profile distortion.

Bending performance of large mode area multi-trench fibers [PDF]

Optics Express, 2013
Bending performance of the Multi-trench Fibers (MTFs) has been investigated using the Finite Element Method. Numerical investigations show that MTFs can provide low-loss effective single mode operation under bent configuration, thanks to the resonant coupling of the Higher order Modes (HOMs).

Influence of Pedestal Fiber Splice on Tm-Doped Fiber Laser Performance

IEEE Photonics Journal, 2023
The influence of Tm-doped pedestal fiber splice on the output performance of a large-mode-area (LMA) Tm-doped fiber laser (TDFL) has been investigated. Arc-fusion induced refractive-index deformation leads to laser leakage from the core to the pedestal ...
