| Outline of Final Research Achievements |
An experiment was performed to observe and reduce radiation pressure noise using a high finesse optical cavity consisting of super-light and regular mirrors. The angular anti-spring effect of radiation pressure, which is a serious problem in this experiment, was investigated. Detailed model was established, the new vibration isolation system was installed, and a new method of measuring the transfer function from the torque of the regular mirror to the angle of the super-light mirror was performed. A new laser power measurement system using radiation pressure was also developed.
