This week we measured the beam radius after EOM. The measurement started from 100mm after EOM. We took 6 points and used Gaussian beam formula to fit. The result is shown as below.
The beam waist is 2.61667926e-05(m). We set the position of EOM as origin, the position of beam waist is 4.72853283e-02(m).
