Both the analyzer cavity and reference cavity are able to be locked, and were simultaneously locked for a while yesterday . However, the temperature control loop is not working because the computer is not seeing the temperature data, so it didn't stay locked . But now we know it's possible !
The mirrors, beam splitter, and photodetectors are set up and aligned to measure the beat of the two signals and I am currently working on mode matching to get the beams the same size at the photodetector.
FSS_RCTRANSPD and ACAV_TRANSPD have been calibrated:
FSS_RCTRANSPD = 1.98 mW/V
ACAV_TRANSPD = 2.18 mW/V |
