Overview

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