论文摘要
我们通过将飞秒脉冲以100 $ $ $ m m核直径为正常的分散液，证明了1700 nm的低噪声，跨国红外的超级智能从1700到4800 nm的产生。我们对整个超脑频谱的强度噪声进行了系统的研究，并表明泵激光器的初始波动最多被放大了三倍。我们还与具有相似核心尺寸的多模氟化物纤维的异常分散液体中产生的八度跨度超局部的噪声特性进行了比较，并表明多模质基因元素纤维中的全normalormal分散型超脑纤维具有卓越的噪声特征。我们的结果为许多实际应用开辟了新的视角，例如长距离遥感，高功率和低噪声至关重要。
We demonstrate the generation of a low-noise, octave-spanning mid-infrared supercontinuum from 1700 to 4800 nm by injecting femtosecond pulses into the normal dispersion regime of a multimode step-index chalcogenide fiber with 100 $μ$m core diameter. We conduct a systematic study of the intensity noise across the supercontinuum spectrum and show that the initial fluctuations of the pump laser are at most amplified by a factor of three. We also perform a comparison with the noise characteristics of an octave-spanning supercontinuum generated in the anomalous dispersion regime of a multimode fluoride fiber with similar core size and show that the all-normal dispersion supercontinuum in the multimode chalcogenide fiber has superior noise characteristics. Our results open up novel perspective for many practical applications such as long-distance remote sensing where high power and low noise are paramount.
