摘　　要：本文报道了DCM增强C3H6O受激拉曼散射荧光增强特性研究结果。实验测量了在不同的DCM浓度、不同的泵浦激光强度以及不同的Stokes入射信号条件下Stokes波输出能量,发现当DCM浓度为2×10-4mol/L时,Stokes波最大增强因子达到5.7,Stokes强度随入射激光增强而增强,过强的Stokes输入信号则可能导致Stokes波增益饱和。The efficient amplification of SRS in Acetone enhanced by DCM dye fluorescence and the amplification characteristics were reported in this paper. Under the various concentration of DCM, various intensity of input Stokes signal and various pump laser intensity, the input and output Stokes wave intensities were measured respectively in the experiment. At the concentration of 2 × 10^-4 mol/L for DCM solution in ethanol, the biggest enhancement factor of Stokes wave was reached to 5.7. The more intensity of pump laser or input Stokes signal, the more intensity of output Stokes wave, and if input Stokes is too great, the enhancement coefficient may decrease named enhancement saturation.
