The optical Kerr coefficient of probe beam (in units of ∑ m ) with pump beam on-resonance. (a) The optical Kerr coefficient and nonlinear absorption as functions of probe-exciton detuning Δ s in the case λ=0. (b) The optical Kerr coefficient and nonlinear absorption as functions of probe-exciton detuning Δ s in the case λ = 2 GHz.
