Splitting Effect

We illustrate the experimental observations of Autler-Townes splitting and the spatial splitting in an electromagnetically induced transparency window in a atomic vapor system of D1 line. As the power of the dressing laser beam changes, we study first-order and secondary Autler-Townes splitting. The influences of these dressing beams, which lead to the larger spatial splitting of four-wave mixing and the shift of probe transmission signal with by changing frequency detuning. Studies on such controllable Autler-Townes splitting and spatial splitting effect can be very useful in applications of spatial signal processing and optical communication.
