    Figures & Tables(4)
    Schematic diagram of a spin–oscillator system of a magnetized clamped-free NR coupled to the electronic spin associated with an NV center in diamond in the presence of a strong pump laser and a weak probe laser.
    The optical Kerr coefficient as a function of the detuning of the probe field from the exciton resonance with three vibrational frequencies of NR ωn = 0.8 MHz, ωn = 1.0 MHz, and ωn = 1.2 MHz for Ω2 = 81(kHz)2, Δc = 0, γn = 10−3 kHz, and g0 = 40 kHz.
    (a) The optical Kerr coefficient as functions of the probe field from the exciton for different coupling strengths. (b) The detailed parts of the left peaks in panel (a). (c) The optical Kerr coefficient as functions of the probe field from the exciton with several different decay rates. (d) The detailed parts of the left peaks in panel (c).
    The optical Kerr coefficient without anything else and with 10 or 30 DNA molecules on the surface of NR. The inset shows the relationship between the frequency shift of NR and the number of added DNA molecules.
