OPO locked on double resonance and seed transmission came through SQZT6 OK

Sheila, Nutsinee

To prep for tomorrow beam check we made sure we could lock OPO on double resonance and see the bright seed beam transmitted onto the SQZT6. We aligned the VOPO platform and ZM1, cranked up OPO gain to 15dB (was -17) and reduced the pump light trigger level. All the working value for OPO in-air lock is now in guardian, simply request LOCKED_SEED_HIGH on the SQZ_OPO guardian when we are ready to go tomorrow.
