AN002: Pound-Drever-Hall Locking with the FSC

Download Whitepaper
This Application Note details how to set up a laser-locking apparatus for frequency stabilisation and linewidth reduction using the Pound-Drever-Hall (PDH) technique, which can be used to perform highbandwidth locking suitable for many applications requiring a stable laser frequency. The Note focusses on practical implementation of working with a high-finesse cavity and locking the laser at an arbitrary frequency.
