| Outline of Final Research Achievements |
We have developed novel design of sensing technique for alignment control of the laser interferometer mirrors, by introducing modified Gouy phase inside cavities. We could give a drastic solution for outstanding problem known as signal degeneracy of the traditional designed degenerated cavities, and proceeded the proof-of-principal experiment. As the sensing simulation using KAGRA parameters confirmed to give similar effects, we have proceeded the experiment: the design and fabrication of the optical, mechanical and control systems.
