11. Note that P will be frequency-dependent, since the Pockels cell acts on phase rather than frequency.
12. Excess noise below 1 kHz is also contributed by unrelated sources, including spurious interference ("feedback") between the 40 m cavity input couplers and the MC output coupler.
13. This measurement was done within minutes of measuring the effective frequency stabilization. This was necessary because the magnitude of the Pockels cell AM effect depended on temperature, changing significantly with a time constant of 10-30 min. The interaction strengths have been corrected for the mean light power on each photodetector, which increases when the cavities are not resonating.
14. The falloff in gain at frequencies below 1 kHz is a residual effect of the feedback path to the end mass of the primary cavity, which was introduced to augment the dynamic range at very low frequencies but does not stabilize the frequency of the light.
