Investigation of amplification characteristics of SRS in acetone enhanced by DCM dye fluorescence

Abstract

The efficient amplification of stimulated Raman scattering in Acetone enhanced by dicyanomethylene(DCM) dye fluorescence and the amplification characteristics are reported in this paper. Under the various concentrations of DCM, various inte nsities of input Stokes signal and various pump laser intensities, the input and output Stokes wave intensities are measured in the experiment. At the concentration of 2×10 -4 mol/L for DCM solution in ethanol, the bigg est enhan cement factor of Stokes wave reaches 57 The higher the intensity of pump l aser or input Stokes signal, the higher the intensity of output Stokes wave, an d if the input Stokes is too high, the enhancement coefficient may decrease, the so-called enhancement saturation.
