摘要：
The enhancement of stimulated Raman scattering (SRS) of weak-gain Raman modes is demonstrated by overlapping the Stokes wavelengths of the Raman modes with Dye lasing gain. Four SRS spectral lines related to C-H stretching modes of ethanol in a similar to 10(-5) mol/L Rhodamine 640-doped ethanol pendant drop can be observed, which are supported by the lasing gain of Rhodamine 640. The dye lasing is found to be partially and even totally suppressed by the intense SRS of ethanol as the pump intensity increasing from 1.2 x 10(8) W/cm(2) to 3.3 x 10(8) W/cm(2).
