Laser-cavity frequency locking using modern control
Elanor H. Huntington, M. R. James, Ian R. Petersen
This paper considers the application of LQG control theory to a problem of cavity locking in quantum optics. Using an equivalence between quantum LQG control and classical LQG control, this problem is reduced to a standard LQG control problem. The cavity locking problem involves controlling the error between the laser frequency and the cavity frequency. A model for the cavity system is set up and an LQG controller is synthesized.
