Pa. Apanasevich et al., ELIMINATION OF SIGNAL FLUCTUATIONS IN CARS OF WEAK RESONANCES IN LIQUIDS, Journal of Raman spectroscopy, 24(9), 1993, pp. 597-598
A technique for decreasing the influence on spectra of CARS signal flu
ctuations was tested experimentally. The proposed technique is based o
n the normalization of the detected CARS signal to the reference signa
l which is generated simultaneously in the same volume of interaction
through four-wave mixing of two exciting beams in a Kerr-shutter confi
guration.
