High nonlinear fibers with low zero‐dispersion wavelength (ZDW), high laser power tolerance and large band‐gap are urgent for all‐optical‐band supercontinuum (SC) generations. Widely used chalcogenide fibers usually have a large ZDW and low laser power tolerance, and thus are not ideal for such purpose. Here, an ultra‐low material ZDW chalcohalide (ChH) glass fiber with high nonlinearity as well as high laser power tolerance has been fabricated successfully via a novel peeling‐off‐extrusion method. The step‐index fiber has double‐cladding structure, the inner cladding is GeGaSe‐CsI glass and the outer one is GeSbS jacket. The core glass has an ultra‐low material ZDW of 3.5 μm and large absorption edge of 2.0 eV. The nonlinear refractive index is 6.67 × 10⁻¹⁸ m²/W @1.55 μm. Broadband SC generation covering 1.05‐13.0 μm is demonstrated in this novel ChH fiber. Such glass fiber with high nonlinearity, wide transparent range, low ZDW and high laser damage threshold is promising for the applications in the mid‐infrared.

高非线性度和低材料零色散的新型卤化卤纤维

具有低零色散波长（ZDW），高激光功率耐受性和大带隙的高非线性光纤对于全光波段超连续谱（SC）世代来说是迫在眉睫的。广泛使用的硫族化物纤维通常具有大的ZDW和低的激光功率耐受性，因此对于这种目的不是理想的。在这里，通过一种新颖的剥离挤压方法成功地制造了具有高非线性度和高激光功率耐受性的超低材料ZDW查卤（ChH）玻璃纤维。阶跃折射率光纤具有双包层结构，内包层是GeGaSe-CsI玻璃，外包层是GeSbS护套。芯玻璃具有3.5μm的超低材料ZDW和2.0 eV的大吸收边缘。非线性折射率为6.67×10 ^-18 m ²/ W @ 1.55微米这种新颖的ChH光纤展示了覆盖1.05-1.30μm的宽带SC生成。这种具有高非线性度，宽透明范围，低ZDW和高激光损伤阈值的玻璃纤维有望用于中红外领域。
