Took Beam size measurement of Probe beam, it had a 1/e^2 of 2.6mm, although I wouldn't be surprised if it was between 2.55 and 2.65, maybe a litte more. The coupling beam were measured a few weeks ago and were each 1.5mm. I took these measurements with the Thorlabs beam profiler.

Interesting things about the localization. When the standing wave is traveling toward the probe beam, meaning the beam on channel ChC is larger than ChB, the data becomes broadened in that direction. I notice that for lower, power coupling beams, 0 to 20 mW. I took data to show this more closely on Oct 31.
 
Weird things happen when I change the Shim current. The features look different but they're still there. Changing the shims affect the total atom number, but doesn't move the atoms in any way, so I don't think it's an alignment issue.
