Femtosecond resonance enhanced CARS for background-free detection of organic molecules Academic Article uri icon

abstract

  • We study the coherent excitation profile (CEP) of resonance enhanced femtosecond CARS in a model system zinc phthalocyanine in a polymer film host as a prospective technique for detection and identification of molecular species in ambient environments. A new method of suppressing the non-resonant FWM background is demonstrated. Transform theory is applied to calculate CEP based on the absorption spectrum, and good agreement between theory and experiment is obtained. 2005 Taylor & Francis Group Ltd.
