Hi! We are observing an excess of frequency noise on the sidebands, which is apparently due to laser noise being shifted by the modulation through an EOM
We would like to try to simulate this, adding some frequency noise on the laser and modulating it.
In particular, we would like to add some noise around 2MHz in the spectrum of the laser, pass through a locked cavity (pre-mode-cleaner) with a pole of 2MHz, then phase modulate the beam and look how this structure is transferred to the sidebands in transmission and reflection of the input mode cleaner cavity (locked)
Do you have any hint on how to simulate this considering the effects of all the loops involved?
