(a) Energy level coupling of the frequency conversion and the pulse sequences of the input light fields, and (b) experimental results about the frequency conversion. The ω _p2 and ω _p3 signals are generated when the ω _c2 field with a frequency of upshifted 203.5 MHz is used to scatter atomic spin coherence.
