摘　　要：由钠蒸气近4D能级双光子共振光谱证实，存在330nm纯参量四波混频信号，共振时参量四波混频抑制了放大的自发辐射，而激光波长失谐时产生的受激超拉曼散射削弱了参量四波混频。There is the pure signal of parametric four-ware mixing (PFWM) in 330 un region, and amplified spontaneous emission is suppressed by PFWM at exact resonance, and PFWNI is weakened by the field associated with stimulated hyper-Ramanscattering at the laser wavelength detuning.They are demonstrated by the spectranear the 4D twophoton resonance in sodium vapor.
