Lab temperature is high again (85 at the particle counter), but apparently hasn't been logging. Attachment 1 is the set of status screens -- still no GPS, and yellow CFC.

Measured beat note with 3 lasers incident on 1611, RF out sent through SLP-21.4 to moku phasemeter

• python [path_to_scripts]mokuPhaseMeterTimeSeries.py -c ch1 -d 450 -i 10.0.5.220 -s veryfast --useInternal --fileType bin --altFileName "L1L2_note"

  • where L1L2 are the lasers being measured (SX, NX, NS)

• DC level on 1611 0.5 mW

• In all three measurements, the phaselock was lost when the beat note drifted too close to DC. I'm trying again with the SLP-100 to give myself some more range.

• really need to put these fibers in a box

While waiting for the measurements,

• requested RF components and a couple items for the EE shop.

Update:

• Now an ASD as described, was PSD
• uploaded current noise data for resistor, battery, and ITC502 driver to git lfs
• Found the proper way to compute the 3CH confidence intervals, but have not yet
