The OFD-X systems smartly deliver a voltage signal that is proportional to the frequency fluctuations of the input laser beam. These turn-key modules are suitable for laser frequency noise characterization and/or for laser frequency stabilization to drastically reduce its optical full width at half maximum linewidth. The OFD-X feature ultralow noise performances that can successfully achieve frequency noise levels as low as 0.01 Hz²/Hz, while remaining in a compact and user-friendly package.
