Abstract:

In the case of other experimental parameters are determined, by further adjusting the phase functions of the pump, stokes and probe lights, the selective excitation of coherent anti-Stokes Raman spectra(CARS) of the CH3 symmetric and asymmetric stretching vibration of methanol solution is achieved. Using the control method proposed by Silberberg, the effect of various adjustable parameters on the selective excitation is summarized by means of parameters adjustment experiments. And according to the relevant theory, the control mechanism of the control method and the approximate range of the best adjustable parameters are qualitatively analyzed. At last, the parameters adjustment method of the selective excitation is summarized.

Key words: quantum optics, selective excitation, parameters adjustment simulation experiments, coherent anti-Stokes Raman scattering
