Abstract

Single-pulse heterodyne CARS (coherent anti-Stokes Raman scattering) detection scheme using shaped femtosecond pulses is one of the most sophisticated approach for managing the problem of non-resonant background disturbance in CARS measurement. However, with the signal processing method conducted in the original report,^1-3 we found that background suppression and resonant peak extraction were sometimes difficult and incomplete. We discuss the reason of this unsuccessful signal processing and propose an improved method for signal extraction realizing the better quality of extracted spectra.
