KAGRA squeezer test

The local oscillator was aligned to the "mode cleaner" (just a single mode polarization maintaining fiber).

The OPO mirrors were cleaned with First Contact after being glued to the new mounts.

It seems one of the ports on the 3 port HVD in the ATC clean booth might be damaged.

We want to perform the nonlinear gain test so we will need to get the OPO PDH signal. We have a mokulab module in TAMA but I need to find the ipad from somewhere.
