OFD: Optical Frequency Discriminator

from €29 900

The ultimate device for easy laser frequency stabilization: compact and affordable.

The OFD system smartly delivers a voltage signal that is proportional to the frequency fluctuations of the input laser beam. This turn-key module is 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 features ultralow noise performances, successfully achieving a frequency noise level as low as 0.01 Hz²/Hz. All this in a compact and user-friendly package.
