Stimulated resonance Raman scattering of Rhodamine 6G.
Stimulated resonance Raman scattering (SRRS) of Rhodamine 6G (R6G) has been observed in microdroplets. By increasing the R6G concentration and input-laser intensity, SRRS from R6G can be distinguished from the R6G lasing. SRRS can be further amplified by the lasing gain when the SRRS is near the peak of the lasing gain profile. When the R6G Raman emission is at wavelengths longer than the lasing envelope, SRRS can still be enhanced by seeding from residual R6G fluorescence.
