The main purpose of the AEI 10 m Prototype is to reach and eventually surpass the Standard Quantum Limit at frequencies ranging from 20 Hz to 1 kHz with a 10 m arm-length Michelson interferometer named the sub-SQL interferometer. The frequency control system uses a 20 m optical path length triangular suspended cavity named the reference cavity, with the goal of suppressing frequency noise of the input laser to a level of similar to 10(-4) Hz/root Hz at 20 Hz rolling off to below 6 x 10(-6) Hz/root Hz above 1 kHz. It is expected that tight angular control of the reference cavity''s mirrors is necessary to reach this stringent requirement.
