PSL LO fiber now directly connected to LO fiber to SQZT6 (outside ISCT6 table)
We now have nearly .4 mW of PSL LO on SQZT6 (used to be just ~100uW). This is plenty of dark noise clearance for SQZ measurement on the homodyne using PSL LO. I didn't measure what comes out of PSL LO fiber recently (measured 1mW on Dec 12). Judging from PSL ref cav transmission power it could be 30% less.
