We present mode-selection in a laser and an amplifier from a multicore Ytterbium (Yb) doped step-index fiber with six large mode area and low numerical aperture (NA) cores, fabricated using a combination of chelate delivery system (CDS) and stack and

We demonstrated that an anti-resonant hollow-core fiber, exhibiting large higher-order mode extinction ratio, works as an efficient spatial mode filter inside a cavity, improving the M2 from 2.09 to 1.39 at 57.7 W laser output.

Linearly polarized ytterbium-doped fiber laser using antiresonant hollow-core fiber inline polarizer
Publikováno v:
Optica Advanced Photonics Congress 2022.
We report an antiresonant hollow-core fiber polarizer integrated into an ytterbium-doped fiber laser cavity to obtain linearly polarized single mode lasing with > 21 dB polarization extinction ratio for up to 25 W output power.

We proposed and demonstrated mode cleaning in a high-power fiber laser by integrating an anti-resonant hollow-core fiber (AR-HCF) into a multimode laser cavity of an ytterbium (Yb)-doped fiber (YDF). An in-house mode-matched AR-HCF was fusion-spliced

We report a linearly polarized ytterbium-doped fiber (YDF) laser cavity configured by integrating an antiresonant hollow-core fiber-based inline polarizer. The 5-cm-long compact fiber polarizer was fusion spliced to a commercial large-mode-area, pola

We present an efficient 976 nm laser from an all-solid Ytterbium-doped multicore fiber. Based on the large core-to-cladding area ratio and wavelength selective bending technique, 25 W output power is achieved with 46% slope efficiency.

We present the first report on a compact, temperature-insensitive, multi-axial mechanical force sensor based on a single-core antiresonant hollow-core fiber (ARHCF). Single-core antiresonant fibers are inherently few-moded in a short length and show

We present an efficient 976 nm laser generation from an ytterbium (Yb)-doped step-index multicore fiber (MCF) with six cores placed in a ring shape. Each of the six cores has a large-mode-area (LMA) and a low numerical aperture (NA), which makes the
