laser shuts down |

[Steve/ Kiwamu]
We found that the laser had completely shut off for ~ 4 hours even with all the PSL doors closed.
We are guessing it is related to the interlock system and Steve is working on it to fix it.
Quote from #6239 |
The 2W Innilight shutdown shut when I opened side door for safety scan. This was not a repeatable by opening -closing side doors later on. Turned laser on, locked PMC and MC locked instantly. The MC was not locked this moring and it seemed that the MC2 spot was still some high order mode
like yesterday. MC lock was lost when the janitor bumped something around the MC.
