Can't get a good standing wave pattern, even though EIT curves look good. I think it might be something with the FORT. It's possibly too inconsistent to see the small change (~20%) I need to see in the standing wave patter. I looked at scans of the Large FORT yesterday and it looks like the signal was oscillating much more than it was when I did EIT before with the D1 line with the 850 nm FORT. I'm going to try to get the 1064 TA FORT working so I can see if the signal from those FORT atoms is more stable.

Need to watch the power out of the TA, I think something might be wrong. Today I have 12.8mW input power and 1.41 Out at 3.106 Amps. I thought I was getting more a few days ago. I also think I need a longer focal asphere to better couple to the TA. I have a very short focal length asphere right now.
