High-contrast interferometry based on anti-Stokes stimulated Raman scattering with broadband and narrow-band quasi-continuous-wave laser light.
Two versions of an anti-Stokes stimulated Raman scattering (SRS) experiment are presented, one with narrow-band light, the other with broadband light. The interferograms exhibit, at optical periods, alternation between complete signal extinction and high signal intensity with much higher contrast than seen in ordinary linear interferometry. Furthermore, for broadband excitation, the envelope of the high-contrast SRS interferogram is limited to an ultrashort time period. Possible applications of such signals for use as switches or logic gates are discussed.
