Abstract

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 100× 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.
