Abstract
Optics is an old and revered subject involving the generation, propagation, and detection of light. In recent years it has become an inherent part of our daily life. With growing emphasis on modern technology, there is a need for new and improved materials as well as sophisticated tools to probe these materials.
In this talk I will discuss our recently developed photoacoustic Z-scan technique. In addition as we are developing efficient molecular photoacoustic contrast agents, multimodal Z-scan characterization results of some of these agents will be presented. Further preliminary photoacoustic tomography studies will be presented demonstrating application of this emerging technology.
