(color online) Real (solid curve) and imaginary (dash curve) parts of the probe susceptibility versus the two-photon detuning δ₁ under the condition of δ₁ − δ₂ = 3γ^′. Parameters are N₁ = N₂ = 5.0 × 10¹² cm⁻³,γ = γ_32,s1 = γ_31,s2 = γ_32,s2 = 5.75/2 MHz, γ^′ = γ_12,s1 = γ_12,s2 = 0.05γ, Δ_s1 = −862γ, Δ_s2 = 862γ, and Ω_s1 = Ω_s2 = 4γ.
