    摘要： One described aspect is an optical fiber comprising: a fiber core that extends along a fiber axis, is configured to transmit a laser energy along the fiber axis, and terminates at a distal end; a first cladding that extends along the fiber axis, is adjacent to the fiber core, and terminates at a distal end; a coating that extends along the fiber axis and terminates at a distal end, wherein the coating is a gold coating; a second cladding that surrounds a portion of the gold coating along the fiber axis, and terminates at a distal end; an outer jacket that extends along the fiber axis and terminates at a distal end; and a fiber tip. Associated laser systems are also disclosed.

    摘要： A multicore fiber includes multiple first linear portions that include a first core portion and a first cladding portion having a refractive index lower than a maximum refractive index of the first core portion and surrounding an outer periphery of the first core portion, and a first tubular portion. The first linear portions are respectively joined to an inner wall of the first tubular portion, and two of the first linear portions are not in contact with each other on a first virtual line connecting centers of the two of the first core portions included in two of the first linear portions on a cross-section perpendicular to the longitudinal direction, at least in a portion in a longitudinal direction.

    摘要： The present disclosure relates to an optical fiber (200) having a core (202) extending along a central axis (206) and a cladding (204) concentrically surrounding the core (202). The core (202) has at least 83-mole percent (mol %) of Silicon dioxide (SiO2) and at most 17-mole percent (mol %) of an up-dopant. And, the cladding (204) has at least 99-mole percent (mol %) of Silicon dioxide (SiO2). Further, the optical fiber (200) has (i) an effective area of greater than or equal to 100 µm2, (ii) a mode field diameter (MFD) in a range of 11 µm to 15 µm, and (iii) a chromatic dispersion of less than or equal to 23.5 picoseconds (ps/(Km.nm) at a wavelength of 1550 nm.

    摘要： The present disclosure relates to an optical fiber (100) with a core (102) extending along a central axis (112), a cladding (104) surrounding the core. The core comprises a first up-dopant and a second up-dopant. And, the cladding comprises a first cladding (106) surrounding the core, a second cladding (108) surrounding the first cladding, and a third cladding (110) surrounding the second cladding. The first cladding has a second up-dopant, the second cladding has down-dopant, and the third cladding is undoped. Further, the first cladding (106) has traces of the first up-dopant and the down-dopant, the second cladding (108) has traces of the second up-dopant, and the third cladding (110) has traces of the down-dopant.

    摘要： The optical fiber comprises a glass fiber including a core and a cladding. The cladding includes an inner cladding surrounding an outer periphery of the core, a trench surrounding an outer periphery of the inner cladding, and an outer cladding surrounding an outer periphery of the trench. The inner cladding has a refractive index lower than a refractive index of the core. The trench has a refractive index lower than the refractive index of the inner cladding. The outer cladding has a refractive index higher than the refractive index of the trench and lower than the refractive index of the core. The core is doped with germanium. The inner cladding has an average chlorine mass concentration of 500 ppm or more and 5000 ppm or less. r2/r1 is 2.2 or more and 3.6 or less, r3 - r2 is 3 µm or more and 10 µm or less, Δ1 - Δ2 is 0.15% or more and 0.40% or less, |Δ2| is 0.10% or less, and Δ3 is -0.70% or more and -0.10% or less, where Δ1 is a relative refractive index difference of the core with respect to the refractive index of the outer cladding, Δ2 is a relative refractive index difference of the inner cladding with respect to the refractive index of the outer cladding, Δ3 is a relative refractive index difference of the trench with respect to the refractive index of the outer cladding, r1 is a radius of the outer periphery of the core, r2 is a radius of the outer periphery of the inner cladding, and r3 is a radius of the outer periphery of the trench. A mode field diameter for light at a wavelength of 1310 nm is 8.8 µm or more and 9.6 µm or less. A bending loss for light at a wavelength of 1625 nm is 1.0 dB or less per turn when the optical fiber is wound on a mandrel having a diameter of 15 mm. A bending loss for light at a wavelength of 1625 nm is 0.1 dB or less per 10 turns when the optical fiber is wound on a mandrel having a diameter of 30 mm. A zero-dispersion wavelength is 1300 nm or more and 1324 nm or less. A cable cutoff wavelength is 1260 nm or less.
