We did a few things to prepare for Kevin's ADF measurements. 

Refrencing the SQZT0 March 2024 Layout...

On SQZT0, we moved SHG Trans. camera back a few inches, we also noticed weird behavior with the camera: when the beam was on the camera it was black, but saturated when the beam wasn't on. 

We unblocked the LO path and aligned BS5 to get the beam on PD 1611. 

Camilla aligned the beam on on PZT 2 (used to control LO phase). 

We walked the beam with MR11 and XMR8 to maximize the power through the LO fiber. Going into the collimator, we had 7.3 mW. Coming out of the fiber after the collimator, we had 3.0 mW of power, then 1.9 mW out of the fiber going into the SQZT7 fiber patch. 

We then decided to clean the fiber tips, including those going into and out of the SQZT0 patch, and the fiber going into the SQZT7 patch, which didn't make a difference in the power. 

After adjusting the strain on the fiber, we had 1.45 mW of power out on SQT7.

We're now ready to set up the balanced homodyne using the SQZ LO independent of the PSL.
