Overview

To lock the detuned RSE configuration (sort of like LIGO-I + signal recycling), all of the interferometer's length degrees of freedom (DOF) are brought under control from an uncontrolled state. Typically this results in resonating the laser field within the resonant cavities formed by the interferomter optics and gives us a configuration which is optimal for audio-frequency gravitational-wave sensitivity.

Recently, our lock acquisition scheme is:

TRX -> ETMX
TRY -> ETMY
REFL33_I -> PRC
REFL33_Q -> MICH
REFL166_I -> SRC
