Large mode area double-layer all-solid anti-resonant fiber for high-power fiber lasers
Results in Physics, 2021 A novel double-layer all-solid anti-resonant fiber (DL-AAF) is proposed to develop large mode area (LMA) fiber for high-power fiber laser applications. Single-mode property and mode field area scaling are investigated in simulations.

Efficient bending compensation of large mode area fiber
SPIE Proceedings, 2014While much research has been developed to achieve very large mode areas (LMA) fibers, many difficulties arise, such as bending losses, mode deformation, and high order modes suppression. The main obstacle which remains difficult to confront in LMA fibers is bending distortion.

Mode instabilities in large-mode-area fiber amplifiers
2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC, 2013The onset of mode instabilities is an effect occurring in high-average-power fiber lasers and amplifiers when their output average power exceeds a certain threshold value [1]. This effect is characterized by a sudden change of the output beam from an initially stable fundamental mode to a regime with more or less chaotic fluctuations between the ...

Large-mode-area Fiber with Non-circular Cores
2018 23rd Opto-Electronics and Communications Conference (OECC), 2018A non-circular core Yb-doped fiber was fabricated in-house. Nearly 200 W output power was obtained with this fiber in a linear cavity. The slope efficiency was 67%. The measured $M_{x,y}^2$ was 1.5 and 3.1, respectively.

Bend distortion in large mode area fiber amplifiers
OECC/ACOFT 2008 - Joint Conference of the Opto-Electronics and Communications Conference and the Australian Conference on Optical Fibre Technology, 2008As ever larger mode area fibers are designed and incorporated into high-power amplifiers, bend-induced mode distortion becomes an important limitation. In any reasonable coiled-fiber arrangement, bend distortion can reduce mode area, gain interaction, and suppression of higher-order modes.
