Waveplates in CLF path moved

Nutsinee Kentaro Lee Daniel

We moved the waveplates in the CLF path further downstreams beyond the pick-off of the launch photodiode and beyond the 5:95 splitter which dumps most of the light going to the fiber.

Since the splitting ratios of these pick-offs are polarization sensitive, the launch power is now independenbt of changes in the fiber polarization. The readback is also more reliable.
