Femtosecond Tunable Wavelength Source System for Multimodal Ultrafast Electron Microscopy and Femtosecond Spectroscopy in Materials for Extreme Environments
Abstract
Funds in the amount of $167,500 are requested for the purchase of a femtosecond tunable wavelength source system for the development of a unique diagnostic capability to investigate the dynamic processes in materials for extreme environments. Currently, an ultrafast transmission electron microscope (UTEM), picoseconds time resolution streak camera with a spectrograph, high energy sub-ns lasers, ultra-sensitive light collection TEM holder, and a diode-pumped femtosecond laser system are all available in our lab to perform simultaneous time-resolved electron imaging and optical spectroscopy for multimodal investigation of the materials of interest to the DoD. The requested funds will be utilized to acquire a broad-band hybrid optical parametric amplifier and free-standing harmonic generator unit, which will drastically improve our diagnostic capabilities. One facet of this proposal, and related current work, is the development of a truly unique capability in the world, multimodal ultrafast TEM, which will provide a platform to perform unprecedented experimental analysis. The motivation for the proposed set of instrument enhancements is to considerably extend the laboratory capabilities to dynamically characterize materials for extreme environments and is also applicable to many other materials and for various applications. A number of ongoing research projects in the PI’s laboratory are directly related to DoD research and development interests and will greatly benefit from the proposed characterization system. This system is also widely applicable to numerous other current DoD projects, both inside and outside University of Connecticut. We anticipate collaborations with numerous other universities and DoD labs because of the unique capabilities that will be developed. In summary, the requested instrumentation complements our current capabilities and would dramatically impact numerous programs and will also greatly benefit the education of our students.
