描述了一种基于Yb光纤的激光梳，重点研究了净腔色散与梳上频率噪声之间的关系，在将净腔色散从反常调谐到正常的过程中，测量了相对强度噪声、偏移频率（f（CEO））线宽以及由此产生的频率噪声谱。我们发现，工作在零净腔色散的激光器有许多优点，包括约100倍的自由运行的f（CEO）线宽和频率噪声功率谱密度相比，正常色散制度。在零色散点处，我们展示了具有低残余噪声的锁相f（CEO）拍频。(C)2011年美国光学学会
We describe a Yb-fiber-based laser comb, with a focus on the relationship between the net-cavity dispersion and frequency noise on the comb. While tuning the net-cavity dispersion from anomalous to normal, we measure the relative intensity noise, offset frequency (f (CEO)) linewidth, and the resulting frequency noise spectrum on the f (CEO). We find that the laser operating at zero net-cavity dispersion has many advantages, including an approximately 100x reduction in free-running f (CEO) linewidth and frequency noise power spectral density when compared to the normal-dispersion regime. At the zero-dispersion point, we demonstrate a phase-locked f (CEO) beat with low residual noise. (C) 2011 Optical Society of America
