We report on the recent progress in the development of digital implementation of Ultrastable Optical Frequency Controls, namely in the frame of experiments based on silicon cryogenic cavity, spherical Fabry-Pérot cavity, compact Ultra- Low Expansion (ULE) cavity and fiber link active compensation. With enhanced capabilities offered by the undersampling technique, we demonstrate similar performances but with a net gain in reconfigurability, flexibililty and dissemination over their analog counterpart.
