Green Laser Injection for Arm Pre-Lock
We plan to install green lasers, which are phase locked to the PSL laser, at each end station to pre-lock the arm cavities before the lock acquisition.
Basic Concept
Noise Requirements
I'd say the arm cavity length should not change more than 1/100 of the resonance width in the time scale of 10sec. For this to be fulfilled, the RMS change of the cavity length must be suppressed below 1e-11m level. Does this make sense ?
