Interesting. My understanding is that this is close to signal recycling, rather than resonant sideband extraction. Is that correct?
For signal recycling, we need to change the resonant condition of the carrier in the SRC. Thus the macroscopic SRC length needs to be changed from ~5.4m to 9.5m, 6.8m, or 4.1m.
In the case of 6.8m, SRC legnth= PRC length. This means that we can use the PRM (T=5%) as the new SRM.
Does this T(SRM)=5% change the squeezing level? |
