Print this reportComment to Polarization in the centeral interferometer likely messed up (9314)According to http://klog.icrr.u-tokyo.ac.jp/osl/?r=9300
the laser power reflected from ITMs (S and P polarized power were
combined) was already different.
So, can we suspect that the injected beam itself toward BS has P-polarized part for BS because the miss-matched injection results in unbalance between transmitted power and reflected power at BS ?
