Frequency stabilization system for a sub-SQL experiment with the AEI 10 m Prototype — •Fumiko Kawazoe for the 10m Prototype — Max-Planck-Institut für Gravitationsphysik (Albert-Einstein-Institut), 30167 Hannover, Germany
The AEI 10 m Prototype Interferometer is will provide a test-bed for very sensitive interferometric experiments, such as the sub-SQL interferometer. It will test new techniques to reach and even surpass the Standard Quantum Limit. In order for the sub-SQL interferometer to achieve the required sensitivity all limiting noise sources need to be suppressed sufficiently. Laser frequency noise will be the main focus of this presentation. The AEI Prototype Interferometer will use a laser frequency stabilization system composed of a 12 m high-finesse triangular frequency reference cavity. The mirrors of the cavity are individually suspended from triple pendulum systems. The laser frequency noise will be suppressed to a level of 10−16 to < 10−18 m/√Hz, from ∼ 20 Hz to 1 kHz in terms of a reference-cavity length-noise.
