I think something is wrong with the beam coming from ChB. I can move the ChC beam to the ChB fiber launch and get very similar data. I took some data on Jan 9 about this. I should look at the fiber output and make sure it's anice gaussian mode. I might switch fibers and redo timings too. The output looks fine on the camera, but it's still something to try. The ChB beam was not transferring as many atoms with EIT as the ChC beam was. the powers were the same and the fact the ChC beam did similar transfers and similar powers from each fiber launch means the beam sizes are correct.
I checked the timings of the ChB beam and it looked really

Light from the ChB AOM set up transfers less atoms the the ChC set up. It's something with the AOM timings or something with the fiber.
I'm convinced that CHC transfers better, but I'm not sure why. I'm going to move the circuit that pumps everything to F=1 to the CHB AOM to see if that circuit is messing things up.
