I've decided to try the experiment with longer EIT pulses. Up until now, I've only tried EIT with a ~50 ns pulse probe beam and ~100 ns pulse coupling beam. I think there are weird effects happening in the fall time of the of both pulses. During this time, the standing wave has different min and max powers and can be transferring atoms in areas other than the nodes of the original standing wave. The pulse shapes were accounted for in the simulations that Deniz ran, but maybe I'll see a more narrowing. I'm trying with a 100 ns probe and 150 ns coupling.

I get good transfer with only 2 mW of probe, and 3 mW of coupling.
