End X ready for a peak down the arm
Lisa, Sheila
We went down to end X, turned on the laser, adjusted the fiber polarization, adjusted the laser temperature to find the beat note, tuned up the beat note alignment, and the PLL is now locked. The QPD servos are also locked.
There is 6.5 mW on the PLL BBPD, the medm screen reports -5.6 dBm beat note strength, and the laser temperature is 28.96 C.
