M2 factor for evaluating fiber lasers from large mode area few-mode fibers

open access: yesFrontiers in Physics, 2023
Evaluating the laser quality accurately is one of the most important and fundamental physical issues for laser sources, and the beam quality of lasers from the large mode area few-mode fibers have been haunted by the presence of high order mode for many ...

Bend-resistant octo-wing silica segmented cladding fiber with high index rings

open access: yesResults in Physics, 2022
We have proposed a novel segmented cladding fiber (SCF) design and the bending effects were investigated in detail. The proposed SCF with large mode area properties has a uniform circular core and octo-wings of rods with higher refractive index than the ...

Bend-resistant leaky multi-trench fiber with large mode area and single-mode operation. [PDF]

open access: yesPLoS ONE, 2018
A novel structure of modified multi-trench fiber (MTF) with characteristics of bend-resistance and large mode-area is proposed. In this structure, each low refractive-index trench of traditional MTF is broken by two gaps up and down.

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

open access: yesIEEE 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 ...

Large Mode Area Fibers for High Power Applications [PDF]

open access: yesOptical Fiber Technology, 1999
We review our recent work toward designing large mode area fibers for high power applications. We show that appropriately designed doped multi-mode fibers can be used to provide robust single-mode output when used in fiber laser cavities. Single-mode (SM) fiber mode field diameters of ~35µm are demonstrated with record SM pulse energies of 0.5mJ at ...

Large-mode-area fibers operating near single-mode regime

open access: yesOptics Express, 2016
Lower NA in large-mode-area fibers enables better single-mode operation and larger core diameters. Fiber NA has traditionally been limited to 0.06, mostly due to the control tolerance in the fabrication process. It has been recognized recently that transverse mode instability is a major limit to average power scaling in fiber lasers.
