[Kokeyama, Enomoto]

We installed a broadband EOM, which is supposed to be used as a frequency actuator until the high power laser unit comes, just before another EOM for PMC locking.
Transmissivity of the broadband EOM was as high as 99.5%.

Current beam profile is shown in the attached figure; two EOMs are on the path.
The beam spot radius at the waist in x direction is a little bit bigger than the designed value, but this deviation is probably acceptable.
