Achieving Gaussian outputs from large-mode-area higher-order-mode fibers

Applied Optics, 2007
We describe an alternative to fiber-gratings for converting higher-order LP(0m) (m>1) fiber modes into a nearly fundamental Gaussian shape at the output of a fiber. This schematic enables the use of light propagation in higher-order modes of a fiber, a fiber-platform that has recently shown great promise for achieving very large mode areas needed for ...

Effective Area Limit for Large Mode Area Laser Fibers

OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference, 2008
We analyze practical constraints of fibers designs for achieving large mode area and single mode operation for fiber lasers, and provide estimated upper limits for the core diameter and effective area.

Large-mode-area optical fiber for photonic nanojet generation

Optics Letters, 2019
The photonic nanojet (PNJ) generated by a shaped optical fiber tip is an attractive technology for laser micro-machining. The working distance has the same order of size as the fiber core diameter; therefore, multimode (MM) fibers are generally preferred.

Multiring large-mode-area delivery fiber for high power

Applied Optics, 2013
The study presents a novel design of multiring delivery fiber with large mode area for high power. Using a FiberCAD method, we investigated a fiber whose core is surrounded by alternative low- and high-index rings. Based on our calculation, the effective area is 400 μm2 at 1.08 μm, larger than the ~280 μm2 of conventional step-index fiber (20/400). The

Polarization-maintaining, large-effective-area, higher-order-mode fiber

Optics Letters, 2017
Higher-order-mode (HOM) fibers guiding light in large-effective-area (Aeff) Bessel-like modes have recently generated great interest for high-power laser applications. A polarization-maintaining (PM) version of HOM fibers can afford the added possibility of coherent beam combination, improved material processing, and polarization multiplexing of high ...

Novel large-mode area fibers for high power fiber lasers

Advanced Photonics 2016 (IPR, NOMA, Sensors, Networks, SPPCom, SOF), 2016
We review all-solid trench-assisted fiber designs for mode-area scaling in flexible fibers. Our proposed fiber designs offer great potential for power scaling of monolithic single-mode fiber laser systems and for high-brightness laser beam ...
