Kerr - July 12, 2016

Today we first were able to detect a peak with the Spectrum analyzer at the 2f frequency (84. kHz)

After aligning the laser to 45 degrees with the polarizers crossed we then we able to detect a 1f frequency of 42 kHz. Unfortunately it still appeared with the no magnetic field. We are still investigating the papers in order to understand exactly why this frequency is still apparent with no B. The 1f frequency seemed to change with magnetic field change. This fact is not free from skepticism however.

I took the ND filter off the power meter itself in order to clarify the signal even further. There was not much of a change only an overall increase in Amplitude for both peaks.

Here we see the two peaks 1f (42 kHz) and 2f (84 kHz). There is another frequency seen at around 94 kHz. We are still fishing for an explanation of the 42 kHz when there is no magnetic field present.
