High-nonlinearity frequency doubling generation anti-resonance optical fiber

The invention discloses a high-nonlinearity frequency doubling generation anti-resonance optical fiber, and belongs to the technical field of photoelectrons. The invention provides a high-nonlinearity frequency doubling generation anti-resonance optical fiber which comprises an outer cladding layer, nested capillary tubes are arranged in the outer cladding layer in an array mode, and air is arranged between the nested capillary tubes. The nested capillary tube comprises an outer capillary tube and an inner capillary tube, the inner capillary tube is arranged in the outer capillary tube, and two-dimensional material layers are arranged on the inner tube wall and the outer tube wall of the outer capillary tube and the inner tube wall of the inner capillary tube. The device can be conveniently coupled with an optical fiber optical path system, is high in frequency doubling efficiency, and can be widely applied to the fields of material science, physical chemistry, biomedicine and the like. 本发明公开了一种高非线性倍频产生反谐振光纤，
