Preliminary noise budgets for fibre stabilization |
|
|
Here are some preliminary noise budgets for the FS experiment ... or rather, the setup shown in attached figure. Looks like the laser frequency noise dominates.
Not surprising given that the optical path length difference is ~150m.
The photodiode noise is not particularly high, although if we stabilize the frequency and intensity of the NPRO it might become a factor.
Anyway, the phase and frequency noise plots are attached. Will post references to the origin of the actual curves for the different noise sources soon. |
