Rephasing of optically driven atomic coherences by rapid adiabatic passage in Pr3+:Y2SiO5

摘要

We present experimental investigations of rephasing optically driven atomic coherences, prepared bynelectromagnetically induced transparency in a Pr3+:Y2SiO5 crystal. In particular, we systematically studynrephasing based on rapid adiabatic passage and compare the performance of the latter with standard rephasingnbased on Hahn spin echoes. The data clearly demonstrate the superior performance of rapid adiabatic passage fornany application of rephasing, which suffers from large inhomogeneous broadenings in the medium or inevitablenfluctuations in the experimental parameters.
