Subject: beat PSL - YARM laser  

[Suresh, Katrin]

Measured frequency fluctuation of the beat between PSL and YARM lasers.

Yesterday, it was very tricky to adjust the voltage offset to the slow YARM laser input to achieve the appropriate beat frequency. Today, it was much easier. During measurement beat around 25 MHz. Calibration factor 40 mV per 10 MHz.
