-Possible explanation would be that there was a loose mirror in cavity??
-Maybe I was leaving a laser on when I took the data in March??
Some of the data sets I take drift up or down in Signal strength as I scan the over a range of frequencies to move the standing wave.
Solution - The center frequency I pick do to scans is to give the best transfer at some minimum coupling power. For frequencies around the center, up to about 1 Mhz away, the transfer is still the same for this power.
But, if I scanned the same frequncy with a higher power coupling beam, not only would the transfer be less because of the high power, but the peak transfer would be at slightly different frequency because of the stark shift.
So as I scan over different frequencies for with the standing wave, I'm creating a spatially dependent stark shift across the atoms. So at some frequencies I could transfer more atoms, giving me an overall small signal.
