Digital phase detector


The Mode is a low-noise digital phase detector, ideally suited for laser frequency stabilization and locking to external reference sources. An indispensable tool in laser spectroscopy, optical-atomic clocks, and many other applications requiring superior frequency stability. It can be completed with our ModePID controller to make your system ultrastable.
