The ultimate guide to PDH locking: performing efficient laser frequency stabilization
This ebook explores next-generation tools to help you streamline laser locking and accelerate your workflow.
PDH locking helps researchers match the emitting optical frequency of a laser to the resonating frequencies of a Fabry-Perot interferometer (FPI), which is an optical resonator that consists of two highly reflective mirrors placed facing each other.
In laser frequency stabilization, the PDH technique utilizes a phase-modulated reference beam to detect the frequency of an optical signal and generate an error signal. The laser frequency stabilization system then uses the error signal to provide feedback to the laser and maintain its frequency at a set point.
