The gravitational wave detectors are based on a Michelson interferometer with Fabry-Perot cavities in its arms and recycling part to have longer optical path length and recycling gain respectively. The position and alignment of each mirrors can be easily disturbed with external excitation, therefore, each optical components have to be controlled appropriately around the operational points. However, it is known that "signal degeneration" occur when extracting mirror's alignment signals for laser interferometer with conventional optical layout of coupled cavity Solving this degeneracy is essential for stable operation of the interferometer. The aim of this study is to demonstrate solving degeneracy of coupled cavity system of the laser interferometer in terms of an alignment sensing signal. In this thesis, control system of coupled cavities have been built and demonstrated for length and alignment sensing and control.
