Overview

We will be removing the MOPA and replacing it with a 2W NPRO.
Instead of current shunt, we will change to use an AOM for the fast power stabilization actuator.
We may decide to use a DC coupled servo, with a remotely programmable offset point to be more like the aLIGO system.
Move the reference cavity and its optics to a different pickoff point.
Move the ISS to the end of the PSL table.
Re-engineer the optics for the PSL_POS and PSL_ANG QPDs.
New EOM for triple modulation.
Change the FSS modulation frequency?
Change the FSS RFPD to have a low Q?
Remove the PMC RF modulation (apply it via the NPRO)?
Steel enclosure for the PMC to do temperature stabilization?
