High Stable Optical Fabry-p(?)rot Cavity And Its Application In Cavity Quantum Electrodynamics

Fabry-P(?)rot cavity plays a crucial important role in the atom,molecule and optical physics field.The narrow linewidth laser systems,which are locked on the ultra-stable optical Fabry-P(?)rot cavity by using the Pound-Drever-Hall technology,have a broad application in many fields,such as Rydberg states excitation of atom,optical atomic clock and ion frequency standard.The interaction of atom and light is still the major topic throughout the study of cavity quantum electrodynamics.After the realization of manipulating single atom in the micro cavity and strong coupling with the cavity mode,one of the next steps is the manipulation of multi atoms in the micro-cavity.This thesis focuses on the following topics:1.The brief historical and current development of cavity quantum electrodynamics,and the motivation of manipulating multi atoms in a single micro cavity.2.The basic principle and concept of optical Fabry-P (?) rot cavity and the background of ultra-stable optical Fabry-P(?)rot cavity.We report the experimental scheme of ultra-stable optical Fabry-P(?)rot cavity,and the measured parameters,including the fluctuation of temperature control,the cavity linewidth,the coefficient of thermal expansion(CTE)and the zero-CTE point.3.The second harmonic generation system for exciting Rydberg state of Cesium and the frequency chain for micro cavity locking and atomic signal detecting basing on the ultra-stable cavity.
