(color online) Diffraction intensities of zeroth-order I(θ0) (black solid line), first-order I(θ1) (blue dashed line), and second-order I(θ2) (red dashed-dotted line) versus coupling field intensity Ωs for (a) δ1 = 0.5γ′, δ2 = −1.5γ′; (b) δ1 = 1.5γ′, δ2 = −1.5γ′; (c) δ1 = 2.5γ′, δ2 = −0.5γ′. Other parameters are the same as those in Fig.
