Akutsu-san, Marc, Matteo

In agreement with Akutsu-san we plan to use the ATC clean room to assemble the new OPO.

Fortunately, there is an IR laser installed on one corner that we can use. After the laser source, there are some optics (Faraday Isolator, lenses) so that the beam should be collimated.

The procedure to turn on the laser is the following :

- Connect power supplies

- Turn on the +5V supply (largest black button)

- Press 'stand-by' button on the laser source to get out of the standby mode

There are few components around this laser setup that we can displace for the assembly (scale, forks, pillar) so that with 2 steering mirrors we have enough space to use this laser.

PS :

- We have to bring new clean suits and we can also bring the old ones of this clean room for the next time we clean the clean suits

- we'll need a periscope, beam profiler, mounts, forks, few lenses, safety glasses, etc ...
