Thesis (Ph.D.)--University of California, Davis, 2010.

Coherent anti-Stokes Raman scattering (CARS) microscopy is a power imaging technique that has demonstrated label-free chemically specific imaging. Unfortunately CARS microscopes have typically been confined to the analysis of densely packed lipid structures in biological samples due to an inherent lack of sensitivity. In this dissertation it is demonstrated that the sensitivity of CARS can be improved through the presence of an enhancing resonance. The interaction of the Raman resonance of interest and the enhancing resonance can lead to significantly stronger signals. Here I demonstrate and characterize doubly-resonant CARS (DR-CARS), which relies on two Raman resonances to provide enhanced sensitivity, and surface-enhanced CARS (SE-CARS) which utilizes the plasmon resonance of a metal substrate to dramatically increase the Raman scattering cross-section. It is shown that DR-CARS provides enhanced sensitivity and I put forth evidence that it may be more sensitive than any other label-free coherent Raman technique. It is further shown that by indirectly exciting the plasmon resonance, SE-CARS can provide position sensitive information about adsorbed molecules. I expect that multiply resonant coherent Raman microscopies will significant increase the applicability of Raman techniques to many new biological problems.
