High-Q disk resonators are used to frequency stabilize two fiber lasers. The improved phase noise of the devices is measured by heterodyne detection and compared to theoretical limits set by thermo-refractive noise.
We introduce piezo-electric mechanical control and stabilization of frequency combs produced in novel, laser-machined microresonators. The residual and absolute 1-second-stabilities of the 33 GHz comb spacing are 5×10−14 and ≤1.4×10−12, respectively.
We present an Er:fiber based laser frequency comb spanning 650 nm–2000 nm that employs amplification in Yb:fiber followed by continuum generation. Comb coherence is verified with f-2f interferometry and comparison to frequency stabilized lasers.
