Abstract

We report the development of a stimulated Raman scattering (SRS) converter capable of generating ~10-ps pulses at several wavelengths simultaneously. For the first time, two-color SRS generation is demonstrated on O–H and C–H stretching vibrations in water–acetone and water–ethanol cascade systems. The SRS converter is pumped by 60-ps pulses of the Nd3+:YAP laser second harmonic in an unfocused beam (in traveling-wave mode). The spectral overlap of the generation bands indicates preamplification of the acetone Stokes component by SRS generation in water. The achieved results demonstrate the feasibility of creating multifrequency SRS converters operating in a traveling wave mode based on a combination of liquid gain media. These converters are promising for application in spectroscopy, chemical analysis, and as biharmonic sources for resonant pumping of nanoscale objects, such as viruses.
