Pound Drever Hall Lock-In
Pound Drever Hall Lock-In Project
The Pound Drever Hall, or PDH, Lock-In Project is desinged to prepare students for working with tunable lasers, high frequency electronics, and optical Cavities. The objective of this project, as the name entails, is to uses the PHD technique to lock a tunable laser to a cavity. Both the laser and the cavity will be constructed by the students using suplied parts, allowing the students to learn the theory behind tunable lasers and the logistics of constucting an optical cavity.
The main concept behind the PHD lock-in method is the use of a Cavity to sense the laser frequency and then adjust the laser based on how large the laser-cavity frequency difference is.
