Title: The Innovative Contributions of Robert J Levis
Introduction
Robert J Levis is a distinguished inventor based in Rose Valley, PA (US). He has made significant contributions to the field of spectroscopy and nanoparticle formation, holding a total of 3 patents. His work has advanced the understanding and application of laser technology in various scientific domains.
Latest Patents
One of Levis's latest patents is focused on filament-based stimulated Raman detection. This invention involves an apparatus and methods of Raman spectroscopy in air, where a target region is excited by a laser pump pulse that exceeds the critical power for self-focusing in air. The duration of this pulse is 15 femtoseconds or less. A laser probe pulse, with a duration ranging from 200 femtoseconds to 100 picoseconds and an energy of at least 20 µJ, is directed at the excited target region. The interaction between the excited target region and the laser probe pulse results in stimulated Raman scattering, which is then detected.
Another notable patent by Levis is centered on the control of particle formation at the nanoscale. This invention provides a means to control nanoparticle and nanostructure formation using real-time feedback from nanoparticle characteristic analysis. A closed-loop feedback controller interacts with a substrate using a shaped laser pulse. The substrate can be solid, liquid, gas, or any combination thereof. The characteristics of the produced nanoparticles are measured and compared with desired characteristics. If discrepancies exist, the feedback controller modifies the laser pulse shape, iterating the process until the desired characteristics are achieved.
