Comment to Bypassing pass preparation (3124)

[Nakano, Nagano]

We finished the fine alignment of the bypassing pass.
The mode matching was almost the same as that of the main pass.
We could lock IMC using the bypassing pass (the IMC refl. signal was fed back to Laser PZT).
Now the flip mirror was removed, i.e. the main pass beam goes to IMC, and the bypassing pass was dumped.
If you would like to use bypassing pass for the work after IMC during PMC istallation, please put flip mirror.
