    Precision and Low Noise Signal Generation and Techniques
    Invited Oral

    Here we report an optical frequency divider (OFD), which can realize optical frequency ratio measurement as well as optical frequency division to other desired frequencies. Using the OFD, we measure the frequency ratio between the fundamental and its second harmonic with an uncertainty of 3E-22. Meanwhile, we also demonstrate an optical frequency synthesizer referenced to a Yb optical clock....

    Precision and Low Noise Signal Generation and Techniques
    Invited Oral

    Lasers with long coherence time and narrow linewidth are an essential tool for quantum sensors and clocks. We will report on the progress using low thermal noise crystalline mirror coatings with cryogenic silicon cavities, discuss alternatives for improving the stability, and give an outlook for more reliable, maintenance free and robust cryogenic silicon cavity setups that will enable also...

    Precision and Low Noise Signal Generation and Techniques
    Invited Oral

    Mode-locked Kerr frequency combs generated in nonlinear resonators pumped with coherent monochromatic light have attracted significant attention because of their practical importance associated with their applications in optical and microwave frequency generation, signal synthesis, clocks and others. Dichromatic resonant continuous wave pumping of a nonlinear optical resonator can result in...
