Femtosecond Amplifying and Harmonic Generation System for Ultra-High Frequency Spintronics
Abstract
This proposal aims for acquisition and development of a femtosecond amplifying and harmonic generation system. The proposed integrated instrumentation will provide ultrashort laser pulses with pulse width of < 40 fs, wavelengths tunable from 450 nm to 10,000 nm, and submicron spatial resolution. The proposed acquisition will be integrated with our existing magnetooptical characterization system to provide the needed capabilities for our research programs, which are largely supported by the Department of Defense, Army Research Office, Army Research Laboratory and other relevant offices. Particularly, one of ongoing research programs is a Multidisciplinary University Research Initiatives program, ÒMagnetoelectrics and Spinorbitronics in Topological Heterostructures and SuperlatticesÓ, sponsored by Army Research Office, with the objective to understand the ultrafast dynamics, switching and THz resonances at the topological interfaces and other femto-magnetic nanomaterials and heterostructures. The instrumentation enables the study of physics and mechanisms of highly energy efficient spintronics at ultrashort temporal scales and ultra-high frequencies and at the spatial nanometer scales. Thus the facility will accelerate the progress in basic science and help open up new frontiers in order to resolve the energy and performance challenges in information technologies. The instrumentation will also offer other new opportunities for research combining and integrating coherent nonlinear optics, nanophotonics, nano-spintronics, magnetism, and advanced quantum material sciences. The proposed system will be accessible by several Principal Investigators and many graduate students and postdocs across different participating universities and campuses under the MURI. The educational impact is vast, as students and young researchers will be trained in the highly interdisciplinary areas of physics, photonics, materials science, chemistry, and nanotechnology. This research will help continual advancement in THz and information technologies, that have been a major economic driver and thus it will thus fuel another wave of innovation to enable superior technologies for DoD and for socio-economic growth.
