No optical isolator available.
One used a half waveplate, a PBS, a faraday rotator and a PBS on a rotating mount to build an optical isolator.
the global transmission measured with powermeter equiped with AA-OD1 filter is 3.68 mW
One has to find a way the measure the isolation efficiency !

SBOX table cleaned and Origami 133MHz laser installed.
power measurement with powermeter and AA-OD1 filter (factor 10 of attenuation) = 3.88 mW
