ISCT6 work
  1. Reconnected the OPO and CLF fibers at the table. The fiber extension patches are no longer needed now that ISCT6 is in its final location.
  2. Turned the squeezer laser on.
  3. Reconnected the PSL sample fiber. We seem to have about a factor of 5 less light coming through compared to before. The PSL reference cavity transmission is down by the same amount. So, its alignment needs some tweaking.
  4. Rediscovered that the fiber transmission PD (DC1) is actually after the polarizer. So, it is measuring the light towards the fiber PD and not the light out of the fiber.
  5. Removed the temporary laser controller from SQZT6. The laser on the table is next.
  6. The fibers going to SQZT6 are still curled up on top of HAM5 and need to be reconnected.
