From: Switching suppression and enhancement of fluorescence and six-wave mixing by phase modulation
In each sub-curve, measured probe transmission signals ((a1), (b1) and (c1)), SWM signals ((a2), (b2) and (c2)) and fluorescence signals ((a3), (b3) and (c3)) versus Δ2 (Δ2 is scanned around −Δ1 from −90 MHz to 90 MHz) with E4 blocked.
Each sub-curve corresponds to different fixed Δ1. For (a1)–(a3) ΔΦ1 = 0, for (b1)–(b3) ΔΦ1 = −π/5 and for (c1)–(c3) ΔΦ1 = 3π/5. The other parameters are Δ3 = 0, G1 = 10.85 MHz, G2 = 19.46 MHz, G3 = 16.66 MHz and
