Instrumentation for Quantum and Nonlinear Optical Imaging
Abstract
The funding obtained from this grant was used to purchase a tunable femtosecond laser system for use in the investigator's research in quantum and nonlinear optical imaging. The finding arrived during the first year of the investigator's ARO project on this topic, and the availability of this new facility has contributed greatly to this research project. During the past year, we made the final selection of the laser system, placed the order for the laser, and installed it in our laboratory. The facility is now fully operational. The laser system was selected both because of its immediate relevance to our ARO-sponsored research program and because it is a very versatile laser system that can be tailored to a wide range of immediate and future applications. The short pulse duration produced by this system allows us to study high-intensity effects through use of only modest pulse energies. In this manner, we can avoid problems associated with laser damage and thereby be able to make use of the weaker but more versatile third-order nonlinear optical response for the generation of entangled and other quantum-correlated beams of light. The wavelength tunability of this laser system will allow us to make use of structural resonances in various material systems (such as PBG materials) to allow the large nonlinear response of such materials to be used for the generation of quantum states of light. This equipment will be useful for the education of a diverse group of students.
