You have to post here the TF between the laser current actuator and the PMC trans PD. Then, you should think about how to make an effective servo using a single SR560 (i.e. what poles).

Then when you hook it up, measure the CLG of the whole thing and see if the PMC trans PD noise spectrum goes down as expected.
