I check to see if either beam was clipping the chamber, and it seems that both are missing the chamber and a large amount of the power is going out the otherside.

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 goood.
