Abstract

The invention relates to a fiber laser-based large mode field photonic crystal fiber. The fiber laser-based large mode field photonic crystal fiber comprises a perfect matching layer, a fiber core layer and a cladding layer, wherein the cladding layer is outside the fiber core layer, the perfect matching layer is outside the cladding layer, the cladding layer comprises multiple air holes I with diameters d that are arranged periodically in a regular hexagon, the cladding layer comprises nine air holes II with diameters d2 that are arranged periodically in a septagon and nine air holes III withdiameters d1, the air holes II and the air holes III are distributed at interval, the nine air holes II are separately arranged at nine points of the septagon, the nine air holes III are separately arranged at middle points of nine edges of the septagon, the diameter d of the air holes I is 3mu m, the diameter d2 of the air holes II is 11mu m, the diameter d1 of the air holes III is 5mu m, and adistance Lambda between the cladding layer and the air holes is 15mu m. The fiber laser-based large mode field photonic crystal fiber has characteristics of low consumption, low non-linearity and large mode field area, enables the fiber laser to output lasers of high power and high quality.

Description

technical field [0001] The invention belongs to the technical field of photonic crystal fibers, and in particular relates to a large-mode-field photonic crystal fiber based on a fiber laser. Background technique [0002] Fiber lasers have potential technical advantages and broad application prospects in high-speed, dense wavelength division multiplexing (DWDM) communication systems, high-precision sensing technology, and high-power laser processing, and have become the focus of international academic and engineering circles. Popular research object.
