CC and p-pol beams

We slightly moved the positions of the last lens of the OPO telescope as well as the one of the EOM.

We obtain the 2 characterizations attached to this entry.

The nominal value of the beam inside the OPO should be 36 um so we are now within +/- 1.3 um of the nominal value.

The OPO telescope was adjusted so to have the mean beam radius of 36 um.

The x-axis "0" is the last hole of the rail.

The 2 beams are still superposed as we could see on the beam profiler.
