Measured probe and corresponding conjugate signals versus Δ2 at different Δ1.
(a1,a2) Stokes and corresponding anti-Stokes gain peaks in the seeding channel, respectively. (b1,b2) Conjugate FWM signals corresponding to (a1,a2), respectively. (c1,c2) Measured intensity difference between the probe and corresponding FWM signals related to F = 3 → F′ and F = 2 → F′, respectively. The dotted lines are guides for eyes. (d) Measured images of the probe and conjugate signals corresponding to (a2,b2), respectively. (e1,e2) Intensity dependences on pump detuning corresponding to F = 3 → F′ and F = 2 → F′ transitions, respectively. The squares, triangles and dots are the original experimental observations of corresponding signals and the solid curves are the theoretical predictions.
