The invention is based on a laser device that generates near-infrared light pulses for coherent Raman spectroscopy and microscopy experiments. In particular, there are two fiber laser cavities having a common saturable absorber based on graphene, which ensures the synchronization of the two laser beams. Optical tunable filters in the two branches allow us to scan the difference in frequency of the two pulses.
