Optical Kerr coefficient of probe beam with various Rabi frequencies of pump beam. (a) The optical Kerr coefficient (in units of m) as functions of probe-exciton detuning Δs with pump beam off-resonance(Δp = ωD) and different Rabi frequencies. (b) The detailed part of (a) showed the relation between optical Kerr coefficient and Rabi frequency>
